[0001] None.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] This invention was not federally sponsored.
BACKGROUND OF INVENTION
[0003] 1. Field of the Invention
[0004] The invention generally relates to the field of footwear.
More particularly, the present invention relates to a flexible shoe
which can be rolled up or otherwise compressed for easy carrying.
The preferred embodiment of this invention are dancing shoes and
can, optionally, be made to resemble an expensive, formal shoe a
woman might wear to a wedding or other event in which she might
dance, but the invention is also applicable to men's dress shoes,
and shoes worn by men, women and children in any activity in which
the wearer of standard shoes could develop sore feet. While a
particularly preferred embodiment of this invention used as an
example of the invention throughout this patent is a women's high
heeled shoe, as these are especially uncomfortable and potentially
dangerous for dancing, the invention is intended to provide an
aesthetically acceptable alternative to uncomfortable shoes in any
place of work, living, or entertainment where flexible, comfortable
shoes would be desirable.
[0005] 2. Description of the Related Art
[0006] Dancing is a popular activity at many celebrations,
including birthdays, charity events, school functions, formal
parties, nightclubs, and weddings. For women in particular,
dressing up for such events typically includes wearing fancy and
expensive shoes with heels ranging anywhere from one to four
inches. While these shoes are very fashionable, high-heeled shoes
can be very uncomfortable to wear for extended periods of time and
are not well suited for activities requiring fast-paced movement of
the feet, such as dancing. Generally, when a woman wearing
high-heeled shoes desires to dance at an event, she must either
attempt to dance in the shoes, which can be very uncomfortable and
increase risk of foot and ankle injury, or go barefoot or in her
stockings, neither of which is usually a pleasant or socially
desirable option. Since dance floor surfaces are frequently scuffed
and dirty, sometimes even with glass and other debris, or wet from
drinks being spilled or in the case of an outside setting, recently
watered grass, the removal of one's high heels to dance often leads
to dirty feet or dirty and torn stockings.
[0007] Some women try to avoid the problem of dancing in high heels
by bringing other shoes, such as tennis shoes or slippers, to dance
in. While tennis shoes adequately solve the comfort problem, they
rarely match the woman's dress/outfit as well as the high-heeled
shoes she wore into the event. Further, slippers often have similar
fashion issues, while not providing the comfort and cushioning like
tennis shoes. Also, bringing other shoes presents the additional
problem of having to cart around an extra pair of bulky shoes to an
event, which can be very inconvenient, especially if a person must
leave the event to retrieve the shoes from a hotel room or car.
Because the additional shoes are bulky and cannot be easily stored
in a small bag or purse, if they are not placed in a readily
observable location, they can be left at the event, causing added
inconvenience and possibly a loss of the shoes themselves. It is
also undesirable in some settings for a woman to remove her
expensive, prestigious dress shoes and dance either barefoot, in
tennis shoes, or in stockings.
[0008] Previous inventions have attempted to create dance shoes
that are comfortable for the wearer. However, the majority of these
inventions have not offered the capabilities of being stored in a
small bag or purse. The few shoes that are flexible enough to fold
up for storage in a small bag or purse, however, do not offer the
ability to secure the shoe in the folded position. This creates a
problem of the shoes unraveling or unfolding within the bag or
purse, which creates more inconvenience, takes up valuable purse
space, and may result in damage to the shoes.
[0009] Therefore, there is a present need for a comfortable shoe
that can be worn during various activities, such as dancing, that
can be easily and securely rolled-up and stored within a purse or
small bag when not in use.
[0010] In this respect, before explaining at least one embodiment
of the invention in detail it is to be understood that the
invention is not limited in its application to the details of
construction and to the arrangement of the components set forth in
the following description or illustrated in the drawings. The
invention is capable of other embodiments and of being practiced
and carried out in various ways. In addition, it is to be
understood that the phraseology and terminology employed herein are
for the purpose of description and should not be regarded as
limiting.
BRIEF SUMMARY OF INVENTION
[0011] It is therefore an object of this invention to provide a
shoe that can be comfortably worn for various activities, such as
dancing.
[0012] It is a further object of this invention to provide a shoe
that can be comfortably worn for various activities, such as
dancing, that can be easily rolled-up or otherwise compressed and
stored within a small bag or purse.
[0013] It is yet a further object of this invention to provide a
shoe that can be comfortably worn for various activities, such as
dancing, that can be secured by a heel, toe, or other strap
contained within the shoe and rolled-up and stored within a small
bag or purse.
[0014] Another object of this invention to provide a shoe that can
be comfortably worn for various activities, such as dancing, that
can be secured by an accessory strap attached to the shoe but not
serving a functional role by attaching the shoe to the foot of the
wearer, and allowing a user to roll-up the shoe and store it within
a small bag or purse.
[0015] It is still a further object of this invention to provide a
shoe that can be comfortably worn for various activities, such as
dancing, that can be economically and efficiently manufactured.
[0016] It is a further object of this invention to provide a
fashionable shoe that can be comfortably worn with various formal
wear during various activities, such as dancing, that can be
secured, rolled-up and stored within a small bag or purse.
[0017] Further objects of the invention include providing a shoe
which "mimics" a fashionable, expensive and classy woman's shoe
such that a woman can enter an event that has dancing, discretely
slip off her high heels (or other uncomfortable shoes) and put on
the roll-up version which mimics the look of the high heels and go
dancing with the hope that no one will notice that she has taken
off her high heels. It is envisioned that this same approach can be
used with men's shoes as well.
[0018] Additional objects of this invention include providing a
roll-up shoe which self-inflates through having a sole portion
comprised of two mating sides, a top and bottom, which are attached
at their perimeters such that they form an airtight hollow bladder
section with a valve which can adjustably let air in and out, which
can optionally contain an inner section of compressible foam which
springs into its uncompressed shape upon having air let into
bladder.
[0019] A further object of the invention is to provide a roll-up
shoe which has flexible wires, strips, or springs embedded in the
sole portion or attached to the top or bottom portion of the sole
such that the shoe automatically unrolls and springs into its
uncompressed shape upon a user releasing the heel strap or other
means by which the rolled-up shape is maintained.
[0020] It is still yet a further object of this invention to
provide a new and unique shoe to the field of footwear that can be
worn for various activities and for various purposes such as
exercise classes (i.e. yoga, pilates), hospital shoes for medical
staff and patients alike, weight loss clinics, etc.
[0021] A final object of the invention is to provide a roll-up shoe
which can be manufactured in a variety of qualities, ranging from
1-use disposable shoes to multiple-use, washable shoes.
[0022] These objects and further objects and features of the
invention will be apparent to one skilled in the art from the
disclosure of the present invention as set forth herein.
[0023] The present invention involves a shoe having a flexible sole
portion, a toe restraining portion, and a heel restraining portion.
The sole portion preferably contains a top layer and a bottom layer
secured thereto. A cushioning layer can be included between the top
layer and the bottom layer. The toe restraining portion extends
from one end of one side of the sole portion and can be a strap or
other covering attached on each end to the sole portion. The heel
restraining portion extends from the other end of one side of the
sole portion and is preferably a strap attached on each end to the
sole portion. The sole portion can be rolled up and secured by the
heel or toe restraining portion or any strap attached to the shoe.
Also, the toe and heel restraining portions can be joined by
material that covers the side(s) of the feet to make a ballerina
style type shoe. Alternatively, the sole portion includes an
inflatable/deflatable airtight chamber to provide shoe support
during use and allow rolling-up and storage of the shoe, where the
airtight chamber or bladder may enclose a preformed, compressible
sole comprised of foam, plastic, or another suitable compound such
that the compressible sole can be rolled up into a compact carrying
size, and yet easily self-inflates to its intended size and shape
upon releasing the strap holding the shoe in its rolled-up position
and allowing air into the bladder, preferably through an adjustable
valve and/or pump.
[0024] There has thus been outlined, rather broadly, the more
important features of the invention in order that the detailed
description thereof may be better understood, and in order that the
present contribution to the art may be better appreciated. There
are additional features of the invention that will be described
hereinafter and which will form the subject matter of the claims
appended hereto.

DETAILED DESCRIPTION OF THE INVENTION
[0034] Referring now to the drawings, wherein similar parts are
identified by like reference numerals, FIG. 1 shows a side
perspective view of the preferred embodiment of the roll-up shoe
10. While the preferred embodiment of this shoe is a dancing shoe,
it is also envisioned that the comfort afforded by the roll-up shoe
would also be applicable to men's dress shoes, as well as for
professions, such as emergency rooms, in which a clean, disposable
shoe is desired.
[0035] Shoe 10 includes a sole portion 20, a toe restraining
portion 30, and a heel restraining portion 40. Sole portion 20
preferably contains a top layer 22 and a bottom layer 24. While the
sole portion 20 preferably contains at least two layers, it is
envisioned that the sole portion 20 can also be made of one
material with two sides to it, both where the two sides are the
same and where the two sides are different, such as if one side in
velvet-like to provide comfort to the soles of the feet and the
other side tough and leather-like to provide durability and
traction. Top layer 22 and bottom layer 24 are preferably sewn
together, but can be attached various ways as would be recognized
by one with ordinary skill in the art. Top layer 22 and bottom
layer 24 can be comprised of similar material or can be comprised
of different materials. Top layer 22 and bottom layer 24 can be
comprised of a variety of flexible and lightweight materials
including cotton, leather, cloth, nylon, rubber, vinyl, paper,
polyester, velvet, felt, plastic, lycra, foam, satin, other
cloth-like materials, or other similar materials which would
perform the desired function(s). Sole portion 20 can be designed in
a variety of shapes and sizes depending on the intended use of shoe
10.
[0036] A cushioning layer 26 can be included, optionally, between
top layer 22 and bottom layer 24. Cushioning layer 26 helps to
provide support to sole portion 20. Cushioning layer 26 is
preferably sewn to encompass the entire interior region formed
between top layer 22 and bottom layer 24 and can be comprised of a
lightweight and flexible material including cloth, rubber, sponge,
foam or similar materials. Cushioning layer 26 can also be
comprised, optionally and illustrated in FIG. 3, of a compressible
foam material and include a valve and/or pump, such that when the
valve is opened, the compressible foam material expands and
provides a comfortable cushion for the wearer. When a user is
finished using shoe 10 and desires to roll it up, the user opens
the valve and rolls up shoe 10 while simultaneously compressing the
air out of the compressible foam material. The user can then close
the valve and store shoe 10 for future use in its compacted,
rolled-up form.
[0037] Toe restraining portion 30 extends from one end 28 of sole
portion 20. Toe restraining portion 30 is preferably attached to
sole portion 20 via top layer 22, but can alternatively be attached
to bottom layer 24. Toe restraining portion 30 is preferably
comprised of a thin and flexible material such as cloth, nylon,
rubber, vinyl, paper, polyester, elastic, velvet, felt, plastic,
lycra, foam, leather, satin, other cloth-like materials, other
elastic-like materials or other similar materials which would
perform the desired function(s), to allow toe restraining portion
30 to be easily rolled up into and along with sole portion 20. Toe
restraining portion 30 preferably comprises a strap attached on
each end to sole portion 20. When shoe 10 is rolled up for storage,
toe restraining portion 30 can be used to secure shoe 10 into a
rolled position. However, toe restraining portion 30 can comprise a
variety of designs such as a closed toe design (see FIG. 6), a
ballerina style design (see FIG. 7), or other designs intended to
restrain the toe portion of a wearer's foot to sole portion 20.
[0038] Heel restraining portion 40 extends from the other end 29 of
sole portion 20. Heel restraining portion 40 is preferably attached
to sole portion 20 via top layer 22, but can alternatively be
attached to bottom layer 24. Heel restraining portion 40 is
preferably comprised of a thin and flexible material such as cloth,
nylon, rubber, vinyl, paper, polyester, elastic, velvet, felt,
plastic, lycra, foam, leather, satin, other cloth-like materials,
other elastic-like materials or other similar materials which would
perform the desired function(s). Heel restraining portion 40 is
preferably comprised of a strap attached on each end to sole
portion 20. When shoe 10 is rolled up for storage heel restraining
portion 40 can be used to secure shoe 10 into a rolled position.
Heel restraining portion 40 can comprise a variety of designs such
as a closed heel design (see FIG. 6), a ballerina style design (see
FIG. 7), or other designs intended to restrain the heel portion of
a wearer's foot to sole portion 20.
[0039] In an alternate embodiment, shoe 10 can be designed to be
disposed of after one use or a few uses. In this embodiment, shoe
10 can be comprised of a plastic coated paper material or other
short-lived material. To prevent slippage of shoe 10 during use, a
non-slip surface can be added to the bottom surface of bottom layer
24. In a further embodiment, shoe 10 can also be machine-washable
for either several or multiple uses.
[0040] There are many possible applications for shoe 10. Shoe 10
can be used at doctor's offices, gymnasiums, offices where
professional shoes are required for men and/or women, weight loss
clinics, changing rooms in commercial and medical locations,
hospitals, clinics, or other places where a person may have to
remove shoes for sanitary purposes. Also, shoe 10 can be used at
hotels, on airplanes, at spas, and other places where shoes are
handed out that may not be the right size or be aesthetically
pleasing, and can be made either durable or "single use
throw-away". Shoe 10 can also be used as boot liners for ski and
snowboard boots to allow a user to remove bulky ski and snowboard
boots and comfortably walk to a hotel or restaurant. Shoe 10 can
additionally contain printed matter and be used as souvenirs at
hotels or as party favors at weddings. Further, if made from
waterproof material, shoe 10 can be used as a shower shoe or beach
shoe, offering sun protection, or in cold weather offering another
layer of insulation to the cold weather. In summary, shoe 10 can be
used anywhere someone wishes to remove his/her shoes and still
remain presentable, professional, and/or fashionable.
[0041] FIG. 2 shows a front perspective view of the preferred
embodiment of roll-up shoe 10, rolled up and secured by a heel
restraining portion 40. To secure shoe 10 in a rolled-up position,
a user can roll one end 28 of sole portion 20 towards other end 29
of sole portion 20 and then wrap heel restraining portion 40 around
rolled up portion of shoe 10. Although heel restraining portion 40
is preferably comprised of one strap, heel restraining portion 40
can also be comprised of two sections that can be connected via a
snap, button, hook and loop fasteners, or other connection means as
would be recognized by one with skill in the art. Alternatively,
the toe-restraining portion 30 can be used to wrap up the shoe, or,
one could use any strap or a separate strap that has no functional
purpose on the shoe other than to secure it into a rolled-up,
compact size when not in use.
[0042] FIG. 3 shows a perspective view of an alternate embodiment
of the roll-up shoe 100. Shoe 100 includes a sole portion 110, a
toe restraining portion 120, and a heel restraining portion 130.
Sole portion 110 preferably contains a top layer 112 and a bottom
layer 114. While the sole portion 110 preferably contains at least
two layers, it is envisioned that the sole portion 1 10 can also be
made of one material with two sides to it, both where the two sides
are the same and where the two sides are different, such as if one
side is velvet-like to provide comfort to the soles of the feet and
the other side is tough and leather-like to provide durability and
traction. Top layer 112 and bottom layer 114 are preferably sewn
together, but can be attached various ways as would be recognized
by one with ordinary skill in the art. Top layer 112 and bottom
layer 114 can be comprised of similar material or can be comprised
of different materials. Top layer 112 and bottom layer 114 can be
comprised of a variety of flexible and lightweight materials
including cotton, cloth, nylon, rubber, vinyl, paper, leather,
polyester, velvet, felt, plastic, lycra, foam, satin, other
cloth-like materials, or other similar materials which would
perform the desired function(s). Sole portion 110 can be designed
in a variety of shapes and sizes depending on the intended use of
shoe 100.
[0043] An airtight pocket 116 can be included between top layer 112
and bottom layer 114. Airtight pocket 116 helps to provide support
to sole portion 110. Airtight pocket 116 is preferably sized to
encompass the entire interior or periphery with enclosed center or
heel region formed between top layer 112 and bottom layer 114.
Airtight pocket 116 is preferably inflated by a user blowing air
through a valve 117 and deflated by releasing air from valve 117.
When a user desires to roll up shoe 100, airtight pocket 116 can be
deflated by opening valve 117 and squeezing the air out of airtight
pocket 116 while rolling up sole portion 110. Alternatively, the
air-tight pocket can merely be an empty cavity that can be filled
with air, either blown up by the user's mouth via the valve 117 or
pumped by way of a small hand pump (118), which can be used in
conjunction with or without the valve 117, such that a user of the
invention can adjust the pressure within the cavity.
[0044] Toe restraining portion 120 extends from one end 121 of sole
portion 110. Toe restraining portion 120 is preferably attached to
sole portion 110 via top layer 112, but can alternatively be
attached to bottom layer 114. Toe restraining portion 120 is
preferably comprised of a thin and flexible material such as cloth,
nylon, rubber, vinyl, paper, polyester, elastic, velvet, felt,
plastic, lycra, foam, leather, satin, other cloth-like materials,
other elastic-like materials or other similar materials which would
perform the desired function(s), to allow toe restraining portion
120 to be easily rolled up into and along with sole portion 110.
Toe restraining portion 120 is preferably comprised of a strap
attached on each end to sole portion 110. However, toe restraining
portion 120 can comprise a variety of designs such as a closed toe
design (see FIG. 6), a ballerina style design (see FIG. 7), or
other designs intended to restrain the toe portion of a wearer's
foot to sole portion 110.
[0045] Heel restraining portion 130 extends from the other end 123
of sole portion 110. Heel restraining portion 130 is preferably
attached to sole portion 110 via top layer 112, but can
alternatively be attached to bottom layer 114. Heel restraining
portion 130 is preferably comprised of a thin and flexible material
such as cloth, nylon, rubber, vinyl, paper, polyester, elastic,
velvet, felt, plastic, lycra, foam, leather, satin, other
cloth-like materials, other elastic-like materials or other similar
materials which would perform the desired function(s). Heel
restraining portion 130 is preferably comprised of a strap attached
on each end to sole portion 110. When shoe 100 is rolled up for
storage, heel restraining portion 130 can be used to secure shoe
100 into a rolled position. Heel restraining portion 130 can
comprise a variety of designs such as a closed heel design (see
FIG. 6), a ballerina style design (see FIG. 7), or other designs
intended to restrain the heel portion of a wearer's foot to sole
portion 110.
[0046] FIG. 4 shows a perspective view of the shoe of FIG. 3 in a
rolled up configuration, including airtight pocket 116, rolled up
and secured by heel restraining strap 130. To secure shoe 100 in a
rolled-up position, a user can roll one end 121 of sole portion 110
towards other end 123 of sole portion 110 and then wrap heel
restraining portion 130 around rolled up portion of shoe 100.
Although heel restraining portion 130 is preferably comprised of
one strap, heel restraining portion 130 can also be comprised of
two sections that can be connected via a snap, button, Velcro, or
other connection means as would be recognized by one with skill in
the art. Again, the use of the heel restraining strap is not meant
to be limiting, but it is envisioned that the toe strap, an ankle
strap, an instep strap, or any other part of the shoe that is
roughly circular in shape could be used to secure the shoe into a
rolled-up position. It is also contemplated that a separate strap
attached to the shoe but without a function in keeping the shoe on
the foot of the user could be used for the purpose of securing the
shoe in a rolled-up condition.
[0047] FIG. 5 shows a perspective view of an alternate embodiment
of the roll-up shoe including the inflatable/deflatable airtight
chamber and an alternate embodiment of the roll-up shoe including
flexible wires positioned within the sole portion. It should be
noted that in addition to the wires illustrated in this drawing, a
similar effect could be accomplished by inserting flexible strips
or springs into, or in contact with the sole of the shoe. Shoe 200
includes a sole portion 210, a toe restraining portion 220, and a
heel restraining portion 230. Sole portion 210 preferably contains
a top layer 212 and a bottom layer 214. While the sole portion 210
preferably contains at least two layers, it is envisioned that the
sole portion 210 can also be made of one material with two sides to
it, both where the two sides are the same and where the two sides
are different, such as if one side in velvet-like to provide
comfort to the soles of the feet and the other side tough and
leather-like to provide durability and traction. Top layer 212 and
bottom layer 214 are preferably sewn together, but can be attached
various ways as would be recognized by one with ordinary skill in
the art. Top layer 212 and bottom layer 214 can be comprised of
similar material or can be comprised of different materials. Top
layer 212 and bottom layer 214 can be comprised of a variety of
flexible and lightweight materials including cotton, cloth, nylon,
leather, rubber, vinyl, paper, polyester, velvet, felt, plastic,
lycra, foam, satin, other cloth-like materials, or other similar
materials which would perform the desired function(s). Sole portion
210 can be designed in a variety of shapes and sizes depending on
the intended use of shoe 200.
[0048] A cushioning layer 216 can be included between top layer 212
and bottom layer 214. The cushioning layer can be merely an empty
cavity that can be filled with air, either blown in by the user's
mouth or pumped by way of small hand pump (250), which can be used
in conjunction with or without the valve (251), such that a user of
the invention can adjust the pressure within the cavity. Cushioning
layer 216 helps to provide support to sole portion 210, and works
similarly to how a backpacking sleeping Ensulite (also sometimes
spelled Ensolite or referred to as a Thermarest) pad works, with a
compressed foam interior portion cut to the desired end shape and a
valve (251) which allows air in and out so the foam interior
expands, thereby inflating the interior cavity when air is let in
through the valve (251). The cavity can also be evacuated of air by
pressing down on the sole or rolling it up when the valve (251) is
opened, thereby deflating the interior portion. Then the Thermarest
is compressed by rolling out all the air for easy carrying on the
back of a backpack. Cushioning layer 216 is preferably sewn to
encompass the entire interior region formed between top layer 212
and bottom layer 214. Cushioning layer 216 can be comprised of a
lightweight and flexible material including cloth, rubber, sponge,
foam or similar materials, or a closed section filled with gel.
[0049] Toe restraining portion 220 extends from one end 218 of sole
portion 210. Toe restraining portion 220 is preferably attached to
sole portion 210 via top layer 212, but can alternatively be
attached to bottom layer 214. Toe restraining portion 220 is
preferably comprised of a thin and flexible material such as cloth,
nylon, rubber, vinyl, paper, polyester, elastic, velvet, felt,
plastic, lycra, foam, leather, satin, other cloth-like materials,
other elastic-like materials or other similar materials which would
perform the desired function(s), to allow toe restraining portion
220 to be easily rolled up into and along with sole portion 210.
Toe restraining portion 220 is preferably comprised of a strap
attached on each end to sole portion 210. However, toe restraining
portion 220 can comprise a variety of designs such as a closed toe
design (see FIG. 6), a ballerina style design (see FIG. 7), or
other designs intended to restrain the toe portion of a wearer's
foot to sole portion 210.
[0050] Heel restraining portion 230 extends from the other end 219
of sole portion 210. Heel restraining portion 230 is preferably
attached to sole portion 210 via top layer 212, but can
alternatively be attached to bottom layer 214. Heel restraining
portion 230 is preferably comprised of a thin and flexible material
such as cloth, nylon, rubber, vinyl, paper, polyester, elastic,
velvet, felt, plastic, lycra, foam, leather, satin, other
cloth-like materials, other elastic-like materials or other similar
materials which would perform the desired function(s). Heel
restraining portion 230 is preferably comprised of a strap attached
on each end to sole portion 210. When shoe 200 is rolled up for
storage heel restraining portion 230 can be used to secure shoe 200
into a rolled position. Heel restraining portion 230 can comprise a
variety of designs such as a closed heel design (see FIG. 6), a
ballerina style design (see FIG. 7), or other designs intended to
restrain the heel portion of a wearer's foot to sole portion
210.
[0051] Roll-up shoe 200 optionally further includes several
flexible wires 240 positioned within sole portion 210. It is
envisioned that the flexible wires 240 can be used alone or in
conjunction with the cushioning layer concept. Wires 240 are
preferably comprised of plastic, metal, composite, or springs, but
can be comprised of other flexible and durable materials as would
be recognized by one with ordinary skill in the art. Wires 240 are
preferably positioned to run along the length of sole portion 210
to facilitate the unrolling of sole portion 210 when shoe 200 is
unrestrained by heel restraining portion 230 or toe-restraining
portion 220. It is envisioned, optionally, that the flexible wires
240 and/or cushioning layer 216 will maintain end 219 of sole
portion 210 rigid that only a toe restraining portion or accessory
strap or the shoe itself will be needed to restrain the shoe. Wires
240 can be stitched, glued, formed within, or otherwise attached
within sole portion 210. The wires 240 (or in alterative
iterations, the flexible strips or springs) serve to not only open
up the shoe quickly and efficiently upon the release of the strap,
but also to maintain a certain amount of rigidity in the shoe.
These wires are important to the invention to retain some rigidity,
as by making the invention out of sole materials that are flexible
enough to allow the shoe to be rolled up for storage, the sole
inherently lacks the structural rigidity found in regular
shoes.
[0052] FIG. 6 shows a perspective view of an alternate embodiment
of the roll-up shoe 300 having a sole portion 310, a toe
restraining portion 320, and a heel restraining portion 331, and an
instep strap 330. In this embodiment, toe restraining portion 320
and heel restraining portion 310 comprises a substantially closed
region where in the toes of a wearer are covered by shoe 300. Toe
restraining portion 320 and heel restraining portion 331 can be
comprised of a soft and flexible material such as cotton, cloth,
nylon, rubber, vinyl, paper, polyester, elastic, velvet, felt,
plastic, lycra, foam, leather, satin, other cloth-like materials,
other elastic-like materials or other similar materials which would
perform the desired function(s). Instep strap 330 comprises a piece
of material which attaches to the sole of the shoe and its
beginning and end, and has sides which define its width. Instep
strap can be comprised of the same types of materials which can be
used to manufacture toe restraining portion 320 and heel
restraining portion 331. It is envisioned that the invention can
function properly with various combinations or eliminations of toe
restraining portions, heel restraining portions, and instep straps,
such that an iteration could exist with just a toe restraining
portion and an instep strap, or just a toe restraining portion and
a heel restraining portion.
[0053] FIG. 7 shows a perspective view of an alternate embodiment
of the roll-up shoe 400 having a sole portion 410, a toe
restraining portion 420, and a heel restraining portion 430. In
this embodiment, toe restraining portion 420 and heel restraining
portion 430 both comprise a substantially closed region wherein the
toes, heel and side(s) of feet of wearer are covered by shoe 400.
Side restraining portions 421 can extend in a variety of optional
arrangements from the outer edges of toe restraining portion 420 to
outer edges of heel restraining portion 430. Side restraining
portions 421 can be constructed from similar or different materials
found in toe restraining portion 420 and heel restraining portion
430. Toe restraining portion 420 and heel restraining portion 430
can both be comprised of a soft and flexible material such as
cotton, cloth, nylon, rubber, vinyl, paper, polyester, elastic,
velvet, felt, plastic, lycra, foam, leather, satin, other
cloth-like materials, other elastic-like materials or other similar
materials which would perform the desired function(s).
[0054] FIG. 8 shows a perspective view of an iteration of the
invention in which the roll-up shoe is designed to approximate the
look of a dress shoe, such that a woman using this shoe can wear
her dress shoes to an event likely to have dancing, then replace
her dress shoes with the roll-up shoes and, to the casual observer,
it will not appear as though she has changed her shoes to dance.
While a high-heeled women's dress shoe is used to illustrate this
aspect of the invention, it is envisioned that other women's shoes,
both dress shoes without high heels and casual shoes, as well as
men's and children's shoes, could utilize this feature. This figure
illustrates how a formal, high heeled dress shoe, generally
indicated by 800, can be mimicked by a more comfortable, roll-up
shoe, generally indicated by 810, which can be used for dancing and
other activities for which a high-heeled shoe would not be
conducive. The formal shoe 800 has a sole 801 which has a
pronounced curve 809 from the relatively flat front portion 806 to
the elevated back portion 807. Formal shoe 800 also has a high heel
805 which may be stylish and fashionable, but presents a major
impediment to a user's safe enjoyment of dancing and other
activities requiring substantial movement. Formal shoe 800 has a
specific and distinctive set of toe restraining means 802, heel
restraining means 803, and connections 804 between heel restraining
means 803 and the shoe 800. The roll-up shoe 810 has a sole 811
which is relatively flat compared with the sole 801 of the formal
shoe 800. The roll-up shoe provides for a more enjoyable (and safe)
dancing experience as both the front portion 816 and back portion
817 are on the same plane, as compared with the elevated rear
portion 807 caused by the high heel 805 of the formal shoe 800. The
distinctive set of toe restraining means 812, heel restraining
means 813, and connections 814 between heel restraining means 813
and the shoe 810 are virtually identical to their counterparts in
the formal shoe 800, thereby allowing a user of the formal shoe 800
to substitute in the roll-up shoe 810 for dancing and other
activities where high heeled shoes would present difficulties.
[0055] With respect to the above description it is to be realized
that the optimum dimensional relationships for the parts of the
invention, including variations in size, materials, shape, form,
function and manner of operation, assembly, and use, are deemed
