Description
FIELD OF THE INVENTION
[0001] The present invention relates to an insole that is made of
non-woven fabric and pumice powder is mixed with the fabric so as
to absorb sweat and remove odor from shoes.
BACKGROUND OF THE INVENTION
[0002] A conventional insole is made of foam material and focuses
on the function of comfort. Nevertheless, because the insole is
located in a closed space, the wearer foot presses on a top of the
insole and an outsole beneath the insole, so that the ventilation
is an important issue when designing the insole. Some insole
include holes for convenience of ventilation, only limited result
can be expected. Furthermore, the sweat from the wearer generates
odor. Although a better insole may absorb the sweat, the sweat is
not isolated from air and odor is still generated. Active carbon
particles are used to absorb humidity and limited odor and the
result is not satisfied. Some insole is spread with bactericide
which could stimulate the wearer skin so that it is not welcomed by
the users.
[0003] The present invention intends to provide an insole that mix
pumice powder into the fabric of the insole and the sweat is
combined with the power so as to be isolated from the air.
SUMMARY OF THE INVENTION
[0004] In accordance with one aspect of the present invention,
there is provided an insole that includes a top layer made of
non-woven fabric and pumice powder is mixed with the non-woven
fabric. A soft layer made of foam material is connected to an
underside of the top layer.
[0005] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is an exploded view to show the insole of the present
invention;
[0007] FIG. 2 is a cross sectional view of the insole of the
present invention;
[0008] FIG. 3 is a cross sectional view of the insole of the
present invention disposed in a shoe;
[0009] FIG. 4 shows that sweat is absorbed by the pumice powder in
the insole, and
[0010] FIG. 5 shows odor is escaped from the insole of the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Referring to FIGS. 1 to 3, the insole of the present
invention comprises a top layer 10 made of non-woven fabric and
pumice powder 30 is mixed with the non-woven fabric. A soft layer
20 made of foam material is connected to an underside of the top
layer 10. The pumice powder 30 can be mixed with the foam material
so that it is spread in the soft layer 20 of the insole.
[0012] As shown in FIGS. 4 and 5, the sweat of the wearer is
absorbed by the pumice powder 30 which then becomes particles so
that the wearer may replace a new insole. The odor generated from
the sweat can also be released via the top layer 10 of the
insole.
[0013] The pumice powder 30 is safe to the wearer skin and is
easily combined with the insole.
[0014] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
