Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to shoe inserts and more particularly
to a two-part shoe insert.
[0003] 2. Description of Related Art
[0004] A shoe insert is a removable insole which accomplishes any
of a number of purposes including daily wear comfort, foot and
joint pain relief from arthritis, overuse, and injuries, orthopedic
correction, smell reduction, athletic performance, or even
increasing the wearer's height or correcting for discrepancies in
leg length.
[0005] An endless array of shoe insert is commercially available.
Most insoles of athletic shoes are formed of a cushioning material
(e.g., rubber, foam or the like) whose uppermost surface is covered
by cloth or leather which contacts the sock of the wearer's foot.
One problem with this type of insole is that the rubber or foam
absorbs moisture from the sock like a sponge and does not allow the
sock to dry. The cloth or leather top layer of some insoles are
provided with tiny, spaced perforations to help channel away the
moisture from the sock and provide ventilation, but the moisture is
not prevented from being absorbed by the insole and simply flows
back through the perforations to the sock.
[0006] Notwithstanding the conventional shoe inserts, the invention
is neither taught nor rendered obvious thereby.
SUMMARY OF THE INVENTION
[0007] It is therefore one object of the invention to provide a
shoe insert comprising an upper member formed of a cushioning
material and comprising a plurality of cylindrical first posts on a
bottom, a plurality of first spaces among the first posts, and a
plurality of apertures formed on a portion of either side of the
upper member; and a lower member formed of a cushioning material
and comprising a plurality of bossed holes on a top, a plurality of
cylindrical second posts on the top, and a plurality of second
spaces among the bossed holes and the second posts; wherein the
first posts are inserted into the second spaces with the second
posts and the bossed holes engaging with the bottom of the upper
member.
[0008] The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0019] Referring to FIGS. 1 to 10, a shoe insert in accordance with
the invention comprises the following components as discussed in
detail below.
[0020] An upper member 1 is made of a cushioning material such as
rubber, foam or the like and comprises a plurality of cylindrical
posts 11 on a bottom. A plurality of spaces 12 each is provided to
separate any two adjacent posts 11. A plurality of apertures 13 are
formed on a portion of either side of the upper member 1.
[0021] A lower member 2 is also made of a cushioning material such
as rubber, foam or the like and shaped the same as the upper member
1. The lower member 2 comprises, on a top surface, a plurality of
bossed holes 21 divided into a first section on a rear portion and
a second section adjacent to the toes, a plurality of cylindrical
posts 22 divided into a first section on a toe portion and a second
section on an intermediate portion (i.e., corresponding to the
arched part of the foot), and the second section of the bossed
holes 21 is formed between the first section of the posts 22 and
the second section of the posts 22. A plurality of spaces 23 each
is provided to separate any two adjacent bossed holes 21, two
adjacent posts 22, or adjacent post 22 and bossed hole 21.
[0022] Height of the post 22 is equal to that of the bossed hole
21. Height of the post 22 is greater than that of the post 11. The
upper member 1 may be put on the lower member 2 in a vertical
alignment relationship with the posts 11 disposed in the spaces 23
and the posts 22 and the bossed holes 21 contacted the tops of the
spaces 12 (i.e., the bottom of the upper member 1) (i.e., assembled
as shown in FIG. 4).
[0023] In use, a wearer may put the assembled shoe insole in a
space 31 of a shoe 3. Next, the foot of the wearer may exert a
force to press the upper member 1 against the lower member 2 (as
indicated by arrows P) to elastically deform and shorten the bossed
holes 21 and the posts 22 (see FIG. 8). In FIG. 8, it is seen that
the bossed holes 21 and the posts 22 are compressed greatly to
expand transversely to urge against the posts 11. Also, the posts
11 are slightly compressed when they contact the bottoms of the
spaces 23. In addition, the apertures 13 allow air passing between
a shoe insole (not numbered) of the shoe 3 and a sock (not shown)
worn on the foot of a wearer to aid in drying the sock.
[0024] Weight of the wearer will be transmitted to the shoe sole
via the foot and the shoe insert. Also, substantial portion of the
weight is transmitted to portions of the shoe insert other than the
intermediate portion thereof. Thus, these portions of the shoe
insert are elastically deformed greatly. It is envisaged by the
invention that the greatly deformed bossed holes 21 may transmit
the weight to the posts 22 and the posts 11. This has the benefit
of preventing the foot from being injured.
[0025] It is contemplated by the invention that the upper member 1
may have different thicknesses, and the densities of the posts 11,
the bossed holes 21 and the posts 22 may be different as shown in
FIGS. 5, 6, 10 and 11 in other embodiments.
[0026] While the invention has been described in terms of preferred
embodiments, those skilled in the art will recognize that the
invention can be practiced with modifications within the spirit and
scope of the appended claims.
