SOLE OF ERGONOMIC SHOE SUITING HUMAN FOOT STRUCTURE AND WALKING
Abstract
This invention relates to a highly engineered shoe sole
developed to fit the natural structure of the human foot and
walking gait. By inventing a shoe sole with the heightened outer
part of the shoe heels and lowered on the inner part of the front
portion of the sole, the shoe enables the triple-time stepping by
maintaining his/her feet and the ankle aligned with the shoes when
standing or walking. Also, by naturally shifting the center of the
body inwards from the outer part of the shoes, thus distributing
the body weight evenly to the entire area of the shoe soles, the
shoes reduce fatigue on the foot by absorbing and mitigating the
impact on the foot that supports the body weight, which prevents
and corrects deformed walking habits such as out-toed gaits and
also prevents slipping while walking.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a highly engineered shoe
sole developed to fit the natural structure of the human foot and
walking. To be more specific, by improving the shape of the bottom
part of the sole, the shoe naturally shifts the center of the body
inwards from the outside of the shoe area, disperses the weight
distribution evenly to the entire area of the shoe soles, thus
absorbs and mitigates the impact on the foot that supports the body
weight while enabling the triple-time stepping which is most
idealistic walking method for our body, and also preventing and
correcting deformation of our vertebra that reduces fatigue from
walking and enhances physical growth, at the same time that
corrects out-toed gaits into a proper walking habit.
[0003] 2. Description of the Related Art
[0004] In general, the shoe soles comprise the bottom of the shoes,
and depending on types of the shoes, the heels can be separately
attached or manufactured without the boundaries.
[0005] For example, the rear portions (shoe heels) of formal shoes
are usually separately attached, whereas the shoe heels of athletic
shoes or slippers are without partition.
[0006] Also, the back portion of the shoes can be formed as a part
of the single body in a shoe sole, or can be separately
attached.
[0007] Recently, there are many functional shoes introduced to
correct improper walking habits and among such shoes, there are
various design of which the bottom of shoe soles are formed in a
gradually downward curve.
[0008] The idealistic way of walking is the triple-time stepping,
but the majority of the shoes concentrate the body weight on the
heels of the foot, thus delivering the impact to the vertebra that
results in pain in the waist, shoulders and the neck, and also
deforming the toes and increasing the fatigue from walking.
[0009] For such reasons, the applicant had suggested Korean
Registered Patent No. 239854 (under the title of "Healthful Shoe")
and No. 536050 (under the title of "The Shoe Soles for Triple-Time
Stepping").
[0010] On the previous inventions, part of the rear portions were
removed which caused pain when the cut out part strongly irritated
and caused pain in the middle of the foot when the shoe is put on
for long hours. Also, the cut out parts are slippery when touching
the ground which can result in unintended fall.
[0011] Especially for some types of the shoes, the rear portion is
formed in a downward curve which thickens the shoe sole too much
and results in many problems such as limiting the function of the
actual shoe heels, the variety of design and especially blunting
the senses of the feet that causes more falls.
SUMMARY OF INVENTION
[0012] Therefore the invention is to resolve problems of the prior
technologies stated above. The objective of the invention is to
provide an ergonomically fit shoe sole for walking by
differentiating the thickness of the shoe bottoms and the rear
portion of the shoe sole that touches the ground from the rear part
to the front part of the shoes and thus dispenses the center of the
body from the outside of the shoe to the inner sole areas that
absorbs and mitigates impact on the foot and induces the most
proper and idealistic triple-time stepping, correcting the out-toed
gaits and preventing the deformation of the vertebra.
[0013] To meet the objects stated above, a shoe sole according to
an embodiment of the invention is composed by heightening the outer
side more than the inner side of the rear portion bottom and
lowering the inner side than the outer side of the front portion.
According to an aspect of the invention, there is provided an
ergonomic shoe sole which is fit for the anatomical foot structure
and walking, the shoe sole including: a main body with a bottom
surface that has a flattened part with a certain width from the
outer side, and an inclined part that is gradually lowered from the
flattened part to the inner side, and a shoe heel with the bottom
surface that has a flattened part with a certain width from the
inner side, and an inclined part that is raised from the flattened
part towards the outer side.
[0014] Also, according to another aspect of the invention, there is
provided an ergonomic shoe sole which is fit for the anatomical
foot structure and walking that has a flat surface from the front
end to the rear end with a distinction between a front portion and
a rear portion. In this shoe sole, the bottom side of the front
portion has a flattened part starting from the outer side with a
certain width and an inclined part starting from the flattened part
to the inner side that lowered the thickness of the sole than the
flattened part, and the bottom side of the rear portion has a
flattened part starting from the inner side with a certain width
and an inclined part that heightened the heels toward the outer
side.
[0015] These, and other aspects and objects of the present
invention will be better appreciated and understood when considered
in conjunction with the following description and the accompanying
drawings. It should be understood, however, that the following
description, while indicating preferred embodiments of the present

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0034] The present invention will now be described more fully
hereinafter with reference to the accompanying drawings, in which
preferred embodiments of the invention are shown.
[0035] This invention relates to a shoe sole that naturally
disperses the center of the body from the outside of the shoe
bottom to the inner areas that absorbs and mitigates the impact
when walking, by improving the design of the shoe sole bottom.
[0036] The shoe sole refers to the part of the shoe that directly
contacts the ground, and the shoe sole is variously formed
according to each of its type.
[0037] For example, the bottom of leather shoes consists of the
front portion and the staged rear portion which is heightened to
form the shoe heel, whereas the bottom of shoes such as athletic
shoes have are flattened from the front portion to the rear portion
of the shoes.
[0038] In cases for the bottom of the athletic shoes, it is common
that the surface of the shoe bottoms are embossed to prevent
slipping.
[0039] As for the shoe bottoms with heightened heels, they show
staged forms due to the heightened levels of the rear portions of
the shoe bottom according to the defined height of the shoe
heels.
[0040] In such cases, the rear portions can be manufactured as a
single body with the bottom or may be separately formed and firmly
attached to the shoe bottom in the heel part.
[0041] FIG. 1 is a perspective view illustrating the structure of
an embodiment of the invention, and FIG. 2 is an inner side view of
a shoe sole according to an embodiment of the invention.
[0042] The shoe shown on the figures is the right-foot shoe,
referring from the big toe to the heel of the foot as the "inner
side" and from the little toe to the heel of the foot as the "outer
side."
[0043] This embodiment is a shoe sole with the shoe heel 20 with a
certain height attached to the main body 10 of the shoe sole, and
such typical shoes with the shoe heel 20 are the formal leather
shoes.
[0044] In such cases, the surface of the main body 10 is attached
to the upper surface of the shoe heel 20, thus the shoe sole is
shaped to be heightened toward the rear portion while keeping the
bottom surface of the main body 10 and the shoe heel 20 leveled
with the ground surface to have simultaneous contact with the
ground.
[0045] The most significant features of the shoe sole are that the
bottom part of the main body 10 and the shoe heel 20 are partially
inclined upward or downward both on the vertical direction and
horizontal direction of the sole bottom.
[0046] FIG. 3 is a bottom view of the shoe sole according to the
embodiment of the invention, FIG. 4 is a cross-sectional diagram of
the FIG. 1 along the A-A line and FIG. 5 is a cross-sectional
diagram of the FIG. 1 along the B-B line.
[0047] As illustrated, this embodiment of the invention relates to
the improvements made to the bottom surfaces of the main body 10
and the shoe heel 20 from the conventional shoe bottoms that
maintains a leveled surfaces with the flat ground. To be more
specific, the bottom surface of the main body 10 is gradually
lowered (by reducing the thickness of the sole) from the outer side
to the inner side, and the bottom surface of the shoe heel 20 is
gradually heightened from the inner side to the outer side.
[0048] To explain this in more detail, the bottom surface of the
main body 10 that comprises the front portion of the shoe maintains
a flattened part 11 with a certain width starting from the outer
side toward the inner side.
[0049] The bottom surface of the main body 10 of a customary shoe
is usually shaped in a downward curve from the front portion to the
shoe heel 20 but keeps the flattened bottom surface with the same
height of the sole thickness from the inner side to the outer
side.
[0050] Comparing with the conventional shoes, the bottom surface of
the main body 10 between the inner side and the outer side of this
embodiment of the invention is featured with a flattened part 11 of
a certain width starting from the outer side of the bottom surface,
and then gradually lowering the height of the sole from the
flattened part 11 toward the inner part, thus shaping an inclined
part 12 lower than the flattened part 11. In other words, bottom
surface of the main body 10 is gradually inclined from the
flattened part 11 toward the inner side of the shoe by lowering the
height of the shoe sole, forming the inclined part 12.
[0051] On the other hand, the rear portion (shoe heel) 20 is
oppositely designed from the main body 10, to form a flattened part
21 with a certain width starting from the inner side of the sole,
gradually inclined toward the outer side of the shoe heels by
heightening the heel, thus forming an inclined part 22.
[0052] The width of the flattened part 11, 21 on the bottom surface
of the main body 10 and the shoe heel 20 should consist about 1/3
part of the width between both lateral sides, starting from one
side of the sole, and the most desirable height difference between
the flattened part 11, 21 and the inclined part 12, 22 is 1.about.7
mm.
[0053] On this embodiment, it is more desirable for the shoe sole
of the inclined part 12, 22 to be gradually lowered by reducing the
thickness of the sole toward the front portion of the bottom
surface of the main body 10, and to gradually heighten the shoe
sole by increasing the thickness of the sole toward the rear
portion 20 of the shoe as pointed out by the direction of the arrow
on FIG. 3.
[0054] In this structure, the bottom surface of the rear portion 20
is connected to the lowest bottom surface of the main body 10 and
can be formed without boundary.
[0055] FIG. 6 is a perspective view illustrating the structure of
another embodiment of the invention, and FIG. 7 is a side view of
FIG. 6. In this embodiment of the invention, the rear portion 20
that obtrudes with a certain height from the bottom surface of the
main body 100 is trimmed off and the bottom surface of the shoe
sole that was all flat from the front part to the rear part is
improved for walking.
[0056] In this embodiment of the invention, the surface of the main
body 100 is spread evenly, and the front portion 110 is defined
from a certain reference point of the sole to the toe and the rear
portion 120 is defined from that reference point to the tip of the
shoe heel. And on the bottom, one part of each portion is gradually
curved downwards at the length direction.
[0057] The shoes with sections divided into front portion 110 and
rear portion 120 yet have flattened bottom surface are mostly
athletic shoes, sandals and etc.
[0058] FIG. 8 is a bottom view of the shoe sole according to
another embodiment of the invention.
[0059] As illustrated, there can be a certain boundary between the
front portion 110 and the rear portion 120 but there can be no
evident boundary, and on this embodiment, those portions are
defined with a certain discretionary ratio of the shoe length.
[0060] The border 130 that divides the front portion 110 and the
rear portion 120 is a virtual border that is not shown.
[0061] The feature of this embodiment is that the inclined part of
the bottom surfaces of the front portion 110 and the rear portion
120 are diagonally placed to raise or lower the shoe sole.
[0062] FIG. 9 and FIG. 10 are cross-sectional views taken along the
C-C line and the D-D Line of FIG. 8. As illustrated, the front
portion 110 and the rear portion 120 are divided by the border 130
as shown in another embodiment of the invention, and with this
border 130 as the reference line, the outer side bottom surface of
the front portion 110 has a certain width of a flattened part 111
and the rest of other part at the bottom is gradually lowered
toward the inner side which forms the inclined part 112.
[0063] The rear portion 120 from the border 130 to the tip of the
heel has a flattened part 121 starting from the inner side with a
certain width and an inclined part 122 starting from the flattened
part 121 to the outer side by gradually lowering the shoe sole
outwards. The idealistic ratio of the division that consists the
border 130 between the front portion 110 and the rear portion 120
of the main body 100 should be 65-70%: 30-35%.
[0064] It is idealistic for the flattened parts 111 and 121 of the
front portion 110 and the rear portion 120 to take 1/3 of the width
from each lateral side, and height difference between the flattened
part 111, 121 and the inclined part 112, 122 to be 1-7 mm.
[0065] In this embodiment of the invention, it is desirable for the
height of the sole to be gradually lowered toward the toe of the
front portion 110 and the height of the heel gradually raised
toward the tip of the shoe heel 120.
[0066] Also, in this embodiment, as shown in FIG. 11, it is also
desirable to form the rear portion 120 to be raised by
10.about.20.degree. from the ground.
[0067] In case of leather shoes with shoe heel 20, it can be formed
as a single body with the main body 10 as illustrated on FIG.
12.
[0068] When the shoe heel 20 and the rear portion 120 is raised by
10-20.degree. from the ground, as shown in the FIGS. 11 to 13, the
attached part of the bottom surface of the main body 10 and the
shoe heel 20 and the attached part of the front portion 110 and the
rear portion 120 can be indented, forming indents 13 and 131 to a
certain depth. Especially when the shoe heel 20 or the rear portion
120 is raised on a certain degree from the ground, it should be
connected to the bottom surfaces of the main body 10 and the rear
portion 110 in a smooth curve without edges.
[0069] If the user stands naturally while wearing the shoes with
the shoe sole according to this embodiment, the shoes will be
aligned inwards as shown in FIG. 14. And as the shoes are aligned
inward, fatigues are also reduced due to the weight also being
gathered inward.
[0070] So, the weight is distributed to both feet when standing,
but on each shoe, the weight is gathered inwards that prevents the
weight from being dispersed, enabling it more safe and comfortable
to wear them. Also, in a standing posture, the feet are very
slightly tilted inwards from the foot heel where weight is
supported the most to the main body 10 or front portion 110 that
gathers the feet.
[0071] The feet touches the ground with an angle that is similar to
the angle formed by the both feet when seen from above, thus the
gravity on both feet is balanced and the pressure on each foot is
reduced when both feet are gathered inwards.
[0072] FIG. 15 is a side view illustrating the walking process with
the shoes that has applied shoe soles whose rear portions are
raised from the ground according to the embodiment of the
invention, and FIGS. 16 to 19 are rear views illustrating the
status when walking with the shoes on.
[0073] When walking, the back part of the shoe heel 20 or the rear
portion 120 touches the ground first, which is different from
standing. When the body weight presses the foot as it touches the
ground, the shoe heel 20 or the rear portion 120 of the shoe
touches the ground naturally from the outer side with higher sole
thickness to the inner side with lower sole thickness, gathering
the feet inwards.
[0074] As the body moves forward, the weight supported by the shoe
increases, so the shoe induces the steps that places the feet in a
paralleled line opposed to out-toed steps when the shoe heal 20 or
the rear portion 120 is brought into close contact with the
ground.
[0075] When the body weight is passed down to the shoe heel 20 or
the rear portion 120, the ankle is stretched out straight that
dramatically relieves ankle from the body weight pressure.
[0076] When the flattened part and the inclined part touch the
ground at the same time, the boundary of those parts are slightly
lifted from the ground at a certain height, forming a space S as
illustrated in FIG. 20, and the lifted surface touches the ground
when body weight is passed to the feet as shown in FIG. 21.
Therefore, as the body weight is supported, the impact on the foot
when touching the ground can be absorbed and mitigated by the
lifted space that acts like a cushion, also absorbing and
mitigating the impact on the ankle.
[0077] As the area that contacts the ground moves forward from the
shoe heel 20 or rear portion 120 to the front portion, the body
weight pressure is transferred naturally from the flattened part 21
of the shoe heel 20 or the flattened part 121 of the rear portion
120 to the flattened part 11 of the main body 10 or the flattened
part 111 of the front portion 110, evenly distributing the body
weight to the both feet.
[0078] The center of the body is moved to front of the shoe as it
is transferred to the flattened part 11 of the main body 10 or the
flattened part 111 of the front portion 110, so the body weight
pressure is gradually lessened on the shoe.
[0079] Thus, at the moment just before the shoe takes off from the
ground, the shoe is twisted more inward as the inner side of the
front part of the main body 10 or the front portion 110 which has
the smallest sole thickness.
[0080] By gathering the shoes inward when walking, the shoe
provides flexibility and minimizes the pressure of the body weight
to the ankle.
[0081] If the pressure from the body weight is minimized, the foot
is less fatigued even when walking for a long time, can maximize
prevention of slipping, and also prevent and at the same time
correct the deformed walking postures so called the out-toed
gait.
[0082] Especially by walking properly in for a long time, we can
prevent deformation of our vertebra and at the same time correct
the deformation itself, reduces fatigue during long walks and also
providing the triple-time stepping which is the most idealistic way
of walking for the human body that walks upright.
[0083] As stated above, the shoe sole provides an idealistic
triple-time stepping by aligning the feet, ankle and the shoe in a
straight line when walking or standing due to raising the rear
portion from the inner side to the outer side, and lowering the
front portion of the sole from the outer side to the inner
side.
[0084] Also this invention naturally moves the center of the body
from the outside of the shoe to the inside area of the shoe and
distributes the weight on the entire shoe area that absorbs and
mitigates the impact and reduces fatigue, prevents and corrects
deformed walking habits such as out-toed gaits and prevents
slipping. This invention has a very useful effect of providing an
ergonomic shoe sole that is designed to fit the anatomical
structure of the foot and walking that constantly and naturally
maintains proper walking habits that prevents and corrects deformed
vertebra.
[0085] Although the best mode contemplated by the inventors of
carrying out the present invention is disclosed above, practice of
the above invention is not limited thereto. It will be manifest
