Abstract
A ventilated shoe having an external layer, a reinforcing layer, and an internal layer, with both the external layer and the internal layer being made from a ventilated mesh material. The reinforcing layer provides a structure for reinforcing the shoe, and is generally positioned between a portion of the external layer and the internal layer. The reinforcing layer is sized and configured to permit the transmission of the fitting stress given by the shoes laces on the eyelets, to the sole portion of the shoe, thereby providing the upper portion of the shoe with durability and stability. The reinforcing layer is configured to provide the maximum amount of structural stability and durability to the shoe, while generally being utilized over a minimum area of the shoe in order to provide the shoe with the maximum porosity. The shoe includes stitching that connects the external layer to the reinforcing layer, which does not restrict the free flow of fluid along the internal layer, thereby allowing the fluid to travel along the internal layer and exit the shoe via open areas where a reinforcing layer is not present.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a ventilated sport shoe, more specifically, a durable shoe formed of ventilated layers of material and a reinforcing layer.
2. Discussion of the Background
Many athletic activities require that an athlete perform strenuous activities for a limited period of time under hot weather conditions. Shoes constructed for such sporting activities are generally not very resistant to wear, and in some instances are constructed for use in only one single event, such as in a marathon race. When constructing a shoe it is indeed quasi impossible to reconcile opposite requirements such as lightness, ventilation, and durability. The inventor of the present invention has determined that it would be advantageous to construct a shoe, and specifically a sports and multi-activity shoe, that will allow a foot of a wearer to remain light, cool and dry under such conditions, while retaining high durability.

. The shoe
100
includes three bands
104
on each side that are provided on the exterior of the shoe
100
, and that extend from the shoelaces

.
FIG. 7

200
manufactured by Polo Sport that is constructed using a single layer of mesh material
202
. The shoe
200
includes two reinforcement bands
204
on each side that are provided on the exterior of the shoe
200
, and that extend from the shoelaces

.
The inventor has determined that positioning of bands on the exterior of the shoe is disadvantageous since the exterior of the shoe can occasionally contact other objects. For example, during a runner's stride, the exterior of the shoe on the instep side of the shoe can come into contact with the other leg of the runner, thereby scraping and causing discomfort to the leg. Accordingly, the inventor has determined that in such a shoe construction the selection of the material used to construct the band should be based at least partially on the softness of the exterior of such a band. This softness factor limits that types of materials that can be utilized for the bands, and can require the selection of an expensive material. An additional disadvantage to the shoes depicted in
FIGS. 6 and 7
is that the bands do not provide stability or durability to the remainder of the shoe not covered by the bands.
When constructing shoes made for sporting or multi-activities, the durability of the shoe is particularly important. For example, the shoe should be resistant to abrasion against various surfaces such as rocks, and should be resistant to deformation and general wear. The inventor has determined that such durability issues are not fully addressed in the sport shoes discussed above.
Accordingly, the inventor has determined that a ventilated shoe is needed that will overcome the disadvantages discussed above.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a ventilated shoe that is porous to allow fluids such as sweat and air to flow in and out of the shoe in order to keep the wearer's foot relatively cool and dry.
Another object of the present invention is to provide a shoe with a reinforcing layer that is sized and configured to permit the transmission of the fitting stress given by the shoes laces on the eyelets, to the sole portion of the shoe, thereby providing the upper portion of the shoe with durability and stability.
An additional object of the present invention is to provide a shoe with a reinforcing layer that positioned below an external layer and is configured to provide the maximum amount of structural stability and durability to the shoe, while generally being utilized over a minimum area of the shoe in order to provide the shoe with the maximum porosity.
A further object of the present invention is to provide a shoe that includes stitching that connects the external layer to the reinforcing layer, which does not restrict the free flow of fluid along the internal layer, thereby allowing the fluid to travel along the internal layer and exit the shoe via open areas where a reinforcing layer is not present.
The ventilated shoe according to the present invention includes an upper portion, which generally encloses a foot of a wearer, and a sole portion, which is affixed to the upper portion. The shoe is constructed using an external layer, a reinforcing layer, and an internal layer, with both the external layer and the internal layer being made from a ventilated mesh material. In the preferred embodiment, the external layer is made of mesh with abrasion resistance characteristics, and the internal layer is made of a three-dimensional mesh which is more comfortable to the wearer then mesh. The three-dimensional mesh is a loose configuration of fibers between a soft porous inner layer and an outer porous layer, which provide a porous layer that allows gases, such as air, and liquids, such as perspiration, to travel therethrough and in a longitudinal direction.
The reinforcing layer provides a means for reinforcing the shoe, and is generally positioned between a portion of the external layer and the internal layer. By positioning the reinforcing layer between the external layer and the internal layer, the reinforcing layer is isolated from both the wearer's foot and the exterior of the shoe, which allows the construction of the reinforcing layer to be based solely on the ability of the reinforcing layer to resist traction forces acting on the shoe, rather than aesthetic concerns, abrasion resistance concerns, or over whether the reinforcing layer will create discomfort for the wearer. Thus, this configuration allows the reinforcing layer to be constructed of inexpensive materials. The reinforcing layer can be constructed from non-ventilated material, or from ventilated material. The reinforcing layer is sized and configured to permit the transmission of the fitting stress given by the shoes laces on the eyelets, to the sole portion of the shoe, thereby providing the upper portion of the shoe with durability and stability. The reinforcing layer is configured to provide the maximum amount of structural stability and durability to the shoe, while generally being utilized over a minimum area of the shoe in order to provide the shoe with the maximum porosity. The reinforcing layer advantageously includes one or more openings that define open areas in the reinforcing layer. Since in the open areas within the openings there are only two layers, specifically the external layer and the internal layer, the open areas are more porous than areas that include the reinforcing layer and therefore the open areas allow fluids to travel in and out of the shoe more rapidly than in areas that include the reinforcing layer. The openings have structural members that extend therebetween that are configured to extend from the eyelet holes to the lower edge of the reinforcing layer, thereby transmitting the stresses placed on the eyelet holes of the shoe by shoelaces to the sole portion of the shoe.
The shoe of the present invention includes a means for connecting the external layer, the reinforcing layer, and the internal layer. The preferred means for generally connecting these layers is stitching, although other means for connecting can be used some places in combination with the stitching, such as glue. As compared to glue, which is not breatheable, the use of stitching generally improves signficantly the ability of the layers to allow air, sweat, or other fluids to travel through the porous layers of the shoe, which can help keep the wearer's foot relatively cool and dry.
The present invention includes stitching that extends from the external layer, through the reinforcing layer, and connects to the internal layer. Such stitching is beneficial in that it provides the maximum interconnection between the three layers, and therefore the maximum structural strength. However, such stitching has the tendency to pinch or compress the various layers together, which hinders the free flow of fluids along the individual layers. The travel of fluids along an individual layer is beneficial in that it allows for the distribution of sweat or other fluids over a large volume of layer material and towards more porous areas of the shoe, which allows the layer to dry and cool faster.
The present invention also includes stitching that connects the external layer to the reinforcing layer. Such stitching does not restrict the free flow of fluid along the internal layer, which allows the fluid to travel along the internal layer and exit the shoe via the open areas where a reinforcing layer is not present.
The present invention includes a reinforcing structure by forming stitching lines extending in a direction from the eyelet holes of the reinforcing layer and downward along the structural member of the reinforcing layer to the sole portion of the shoe. The stitching lines transmit stresses placed on the eyelet holes of the shoe by shoelaces to the sole portion of the shoe.
The shoe of the present invention preferably further includes a first secondary reinforcement layer attached on an exterior surface of the external layer at the toe part of the shoe and a second secondary reinforcement layer attached on an exterior surface of the external layer at a heel part of the shoe. The secondary reinforcement layers are constructed to provide protection to the shoe at high contact areas and are made of ventilated material, such as grid or mesh having a high abrasion resistance, such as nylon. The shoe of the present invention preferably further includes a secondary reinforcement layer attached on an interior surface of the internal layer at an eyelet part of the shoe.
The shoe of the present invention preferably includes a tongue portion that includes a layer of ventilated foam positioned beneath the external layer. The tongue portion also includes an inner cleanliness textile that is preferably attached to the foam. The shoe also preferably includes a layer of ventilated foam extending about the ankle portion of the shoe.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, where like reference numerals identify the same or corresponding parts throughout the several views,
FIGS. 1
though
5
set forth various embodiments of a ventilated shoe according to the present invention.
FIG. 1
depicts an embodiment of a ventilated shoe
10
according to the present invention. The shoe
10
includes an upper portion
12
, which generally encloses a foot of a wearer, and a sole portion
14
, which is affixed to the upper portion
12
using, for example, glue and/or stitching. The shoe
10
generally includes a toe part
16
at a forward end of the shoe
10
, and a heel part
18
at a rearward end of the shoe
10
. The shoe
10
further includes an opening
19
that allows the wearer of the shoe
10
to insert a foot therethrough, and that is adjacent to the wearer's ankle once the shoe
10
is properly positioned on the wearer's foot.
As depicted in
FIG. 2A
, the ventilated shoe
10
of the present invention is constructed using an external layer
20
, a reinforcing layer
30
, and an internal layer
40
. Both the external layer
20
and the internal layer
40
are made from a ventilated mesh material. The internal layer
40
generally abuts the wearer's foot
2
(see
FIG. 2B
) or the wearer's sock
4
(see
FIG. 2C
) when the shoe
10
is positioned on the wearer's foot. In the preferred embodiment, the external layer
20
is made of mesh with abrasion resistance characteristics, and the internal layer
40
is made of a three-dimensional mesh which is more comfortable to the wearer then mesh. The three-dimensional mesh is a loose configuration of fibers
42
extending substantially perpendicularly between a soft porous inner layer
41
and an outer porous layer
43
, which provide a porous layer that allows gases, such as air, and liquids, such as perspiration, to travel not only therethrough, but also in a direction substantially parallel to said layers
41
,
43
. Preferably, the three dimensional mesh material has a plurality of holes having a diameter in a range from 0.5 mm to 2 mm, although diameter holes that are either large or smaller than this preferred range can alternatively be used. Preferably, the ventilated mesh material of the external layer
20
has a plurality of holes having a diameter in a range from 0.5 mm to 2 mm, although diameter holes that are either large or smaller than this preferred range can alternatively be used.
The reinforcing layer
30
depicted in
FIGS. 2A
,
2
B, and
2
C provides a means for reinforcing the shoe, and is generally positioned between a portion of the external layer
20
and the internal layer
40
. By positioning the reinforcing layer
30
between the external layer
20
and the internal layer
40
, the reinforcing layer
30
is isolated from both the wearer's foot and the exterior of the shoe, which allows the construction of the reinforcing layer
30
to be based solely on the traction resistance characteristics of the reinforcing layer
30
, rather than aesthetic concerns, abrasion resistance concerns, or concerns over whether the reinforcing layer will create discomfort for the wearer. This configuration allows the reinforcing layer
30
to be constructed of inexpensive materials. The reinforcing layer
30
can be constructed from non-ventilated material such as non-woven material, or from ventilated material, such as breathable woven textiles, or unwoven textiles having small holes. The reinforcing layer
30
is sized and configured to permit the transmission (without deformation of the layer) of the fitting stress given by the shoes laces (not depicted) on the eyelets
22
, to the sole portion
14
of the shoe
10
. Due to its high traction resistance, i.e., low deformation under traction stress, the reinforcing layer
30
also provides the shoe
10
with better durability and better dimensional stability on the upper portion
12
of the shoe
10
. While the reinforcing layer
30
provides durability and dimensional stability to the shoe
10
, the amount of area of the shoe
10
that incorporates a reinforcing layer should be kept to a minimum because the reinforcing layer
30
is not generally as porous as the external layer
20
and the internal layer
40
. One objective of the present invention is to construct a shoe
10
that is porous to allow fluids such as sweat and air to flow in and out of the shoe through the layers in order to keep the wearer's foot relatively cool and dry. The reinforcing layer
30
is preferably constructed to allow fluid to travel therethrough.
FIG. 4A
depicts an embodiment of the reinforcing layer
30
. The reinforcing layer
30
is configured to provide the maximum amount of structural stability and durability to the shoe, while generally being utilized over a minimum area of the shoe
10
in order to provide the shoe with the maximum porosity. The preferred embodiment of the reinforcing layer
30
has an end
31
that is located at the toe part
16
of the shoe, and an end
32
that is located at the heel part
18
of the shoe
10
. The reinforcing layer
30
has a plurality of eyelet holes
34
that correspond to the eyelet holes
22
of the shoe
10
, and an opening
35
that extends about the opening
19
of the shoe
10
. Note, however, that in the preferred embodiment the opening
35
is not flush with opening
19
, but rather dips downward toward the sole portion
14
of the shoe
10
. The reinforcing layer
30
extends downward to a lower edge
38
that abuts the sole portion
14
of the shoe. The reinforcing layer
30
also advantageously includes one or more openings
36
that define open areas in the reinforcing layer. Since in the open areas within the openings
36
there are only two layers, specifically the external layer
20
and the internal layer
40
, the open areas are more porous than areas that include the reinforcing layer
30
and therefore the open areas allow fluids to travel in and out of the shoe
10
more rapidly than in areas that include the reinforcing layer
30
. The openings
36
have structural members
37
that extend therebetween. The structural members
37
are configured to extend from the eyelet holes
34
to the lower edge
38
, thereby transmitting the traction stresses placed on the eyelet holes
22
of the shoe
10
by shoelaces to the sole portion
14
of the shoe
10
. The openings
36
are preferably formed of curved shapes, which prevents a concentration of stresses that would be present in a shape having angled corners. The reinforcing layer
30
can alternatively be constructed to include apertures
39
which give the layer
30
increased porosity. The reinforcing layer
30
preferably extends along both sides of the shoe
10
.
The shoe
10
of the present invention includes a means for connecting the external layer
20
, the reinforcing layer
30
, and the internal layer
40
. The preferred means for connecting these layers is stitching, although other means for connecting can be used in some places or in combination with the stitching, such as glue. As compared to glue, the use of stitching improves significantly the ability of the layers to allow air, sweat, or other fluids to travel through the porous layers of the shoe, which can help keep the wearer's foot relatively cool and dry.
FIG. 2A
depicts a stitch
44
that extends from the external layer
20
, through the reinforcing layer
30
, and connects to the internal layer
40
. The stitch
44
is beneficial in that it provides the maximum interconnection between the three layers
20
,
30
, and
40
, and therefore the maximum structural strength. The stitch
44
has the tendency to pinch or compress the various layers together.
FIG. 2B
depicts in a more detailed way the flow of fluids in the area of a stitch
44
along the internal layer
40
using arrows in a situation where the internal layer is adjacent the wearer's foot
2
. In this situation, the fluid can travel both in a direction parallel to the layers
41
,
43
along the length of the internal layer
40
(horizontally, vertically, and diagonally) through the stitching
44
, and in the space S over the outside of the stitching
44
between the internal layer
40
and the foot
2
.
FIG. 2C
depicts the flow of fluids along an internal layer
40
′ using arrows in a situation where the internal layer is adjacent the wearer's sock
4
. The internal layer
40
′ is constructed of a mesh material which can be similar or different to that used for the external layer
20
. In this situation, the fluid can travel both along the length of the internal layer
40
′ under the stitching
44
, however, the fluid will most readily travel around the outside of the stitching
44
and along the fabric of the sock
4
. In this embodiment, the internal layer
40
is not a three dimensional mesh, to enable the use of the shoe with a sock
4
in such a three dimensional material.
FIG. 2A
depicts a second stitch
46
that connects the external layer
20
to the reinforcing layer
30
. The stitch
46
does not restrict the free flow of fluid along the internal layer
40
, which allows the fluid to travel along the internal layer
40
and exit the shoe
10
via the open areas, for example the open areas defined by openings
36
, where a reinforcing layer is not present. The stitch
46
provides some structural stability and fixes the positioning of the reinforcing layer
30
.

FIG. 3B
depicts exemplary locations for stitching
44
and
46
. The stitching
46
can be used along the boundaries of the reinforcing layer

to the external layer
20
. The stitching
46
can be used along the edges of the openings
36
of the reinforcing layer
30
, and along the opening
35
. The stitching
44
can be used as a reinforcing structure by forming stitching lines
45
extending in a direction from the eyelet holes
34
and downward along the structural member
37
to the sole portion
14
of the shoe
10
, as depicted in FIG.

B. The stitching lines
45
transmit stresses placed on the eyelet holes
22
of the shoe
10
by shoelaces to the sole portion
14
of the shoe
10
. The stresses on the eyelet holes
22
extend in a direction generally coextensive with the stitching lines
45
. The stitching lines
45
define different areas of the upper part of the shoe
10
. Each area preferably includes at least one opening
35
,
36
in the reinforcing layer
30
. As evidenced by arrows F in
FIGS. 2A and 3B
, in each such area, the fluid travels in a direction parallel to the layers
41
,
43
along the length of the internal layer
40
and through the openings
36
.
As depicted in
