Claims
1. An article of footwear comprising: a sole having a heel portion,
a toe portion and a shank portion; a vent; a plurality of pillars
extending upwardly from a base surface of the sole defining air
circulation passageways therebetween; an insole having an upper
surface and a lower surface, the lower surface resting on the
plurality of pillars, the insole further having a plurality of
perforations therethrough intersecting the air circulation
passageways; whereby air is free to circulate between the upper
surface of the insole and the vent through the air circulation
passageways.
2. The article of footwear of claim 1 wherein the insole is
removable.
3. The article of footwear of claim 1 wherein the upper surface of
the insole is covered with a fabric.
4. The article of footwear of claim 1 further comprising an upper
attached to the sole.
5. The article of footwear of claim 4 wherein the upper and sole
comprise a single molding.
6. The article of footwear of claim 1 wherein the lower surface of
the insole has a plurality of channels formed therein.
7. The article of footwear of claim 1 wherein the vent is disposed
in the shank portion of the sole.
8. An article of footwear comprising: a sole; an upper attached to
the sole; a plurality of spaced apart pillars extending upwardly
from a base surface of the sole.
9. The article of footwear of claim 8 further comprising an insole
having an upper surface and a lower surface, the lower surface
resting on the plurality of pillars.
10. The article of footwear of claim 8 wherein the pillars are
configured to correspond to pressure points on a wearer's foot.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates generally to the field of footwear
and, more particularly, to an article of footwear having a sole
constructed for improved comfort and ventilation.
[0003] 2. Background
[0004] Most shoes and other closed articles of footwear suffer from
poor ventilation. When the foot is enclosed in a poorly ventilated
shoe, natural perspiration is trapped, which promotes the growth of
bacteria, fungi and the like. This commonly results in discomfort,
unpleasant odors and skin conditions.
[0005] Many different designs of ventilated footwear have been
proposed. These include various arrangements of air passageways,
some including pumps to provide forced ventilation.
SUMMARY OF THE INVENTION
[0006] The present invention provides an article of footwear having
a sole with a plurality of pillars extending upwardly from its base
surface defining passageways therebetween. The sole may include a
vent, which may be disposed in the shank portion of the sole or
elsewhere. An insole may rest on the plurality of pillars and may
have a plurality of perforations therethrough that intersect the
intersole passageways. Air is thereby free to circulate between the
upper surface of the insole and the vent through the intersole
passageways. The plurality of pillars support the weight of the
wearer and provide superior comfort in comparison to a conventional
sole.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a partially cut away and exploded view of an
article of footwear in accordance with an embodiment of the present
invention.
[0008] FIG. 2 is a bottom plan view of the insole shown in FIG.
1.
[0009] FIG. 3 is a perspective view showing the bottom of the
article of footwear in FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION
[0010] In the following description, for purposes of explanation
and not limitation, specific details are set forth in order to
provide a thorough understanding of the present invention. However,
it will be apparent to one skilled in the art that the present
invention may be practiced in other embodiments that depart from
these specific details. In other instances, detailed descriptions
of well-known methods and devices are omitted so as to not obscure
the description of the present invention with unnecessary
detail.
[0011] FIG. 1 illustrates an article of footwear 10 in accordance
with one embodiment of the present invention. The article of
footwear comprises a sole 12 and an upper 14, the majority of which
is cut away in this view. The article of footwear further comprises
an insole 16, which may be permanently secured to the sole or may
be made removable therefrom. The article of footwear may be
constructed of natural leather, fabric or other natural materials,
such as plantation crepe or vulcanized rubber, or may be
constructed of synthetic materials, such as synthetic leather or
molded plastic.
[0012] A particular type of footwear to which the present invention
may be applied is a closed low-back shoe, sometimes referred to as
a clog. Such shoes are frequently worn by nurses and other
healthcare workers. These shoes are commonly made with the sole and
upper as a single piece molding of resilient plastic. While such a
shoe is one example of an article of footwear embodying the present
invention, the invention is not limited in this regard.
[0013] A vent 18 is fitted in the shank portion of sole 12, but
could be located elsewhere if desired. The vent provides an air
passageway completely through the sole in the arch of the article
of footwear. Vent 18 preferably incorporates a screen or mesh to
prevent debris from entering while still admitting air. The upper
or base surface of sole 12 is covered with a plurality of upwardly
extending pillars 20, which define a maze of interconnecting
passageways 22. These passageways allow air admitted by vent 18 to
circulate throughout the area of the sole.
[0014] Insole 16 includes a plurality of perforations 24 that
intersect the passageways 22. These complete the air circulation
path from the vent 18 into the footwell of the article of footwear.
The upper surface of the insole may have a layer of fabric applied
thereto for the comfort of the wearer.
[0015] With reference to FIG. 2, the lower surface of insole 16 may
be provided with a plurality of channels 26. These channels help
improve the circulation of air around pillars 20.
[0016] Pillars 20 function not only to permit circulation of air
between the sole and insole; the pillars also serve to support the
weight of the wearer and concentrate pressure onto corresponding
locations on the wearer's foot. This provides a gentle massaging
action as the wearer walks. In this regard, the pillars may be
located to concentrate pressure at specific pressure points on the
wearer's foot so as to achieve a therapeutic effect. The pillar
configuration with spaces therebetween and the natural resilience
of the pillars increases the comfort of the wearer in comparison to
conventional sole construction.
[0017] It will be recognized that the above-described invention may
be embodied in other specific forms without departing from the
spirit or essential characteristics of the disclosure. Thus, it is
understood that the invention is not to be limited by the foregoing
illustrative details, but rather is to be defined by the appended
claims.
