Abstract
An insole includes a deformable, resilient cavity that acts as an air pump as the wearer walks or runs while wearing a shoe or other footwear having the insole placed therein. Pressure applied to the insole by the wearer's foot during each cycle of the wearer's gait may depress the air pump, thereby forcing air through channels leading to air outlet holes at the foot bed surface of the insole. As pressure is released by the wearer lifting the foot, the air pump can expand, thereby drawing in air through a one-way air inlet valve.

- Typical footwear may be made of several components. One such component is the insole, the interior bottom of a shoe or other footwear. The insole sits directly beneath the wearer's foot. Numerous insole designs have been implemented to attempt to cushion the wearer's foot while providing adequate foot support, thereby enhancing the comfort of the wearer. Other insole designs are created to absorb perspiration and/or foot odors.

One embodiment ofair pump 130 is adapted to expand back to its original shape when pressure is released. Asair pump 130 expands to its original shape, it can take in air. In one embodiment,air pump 130 is positioned near the rear ofinsole 100 such that it is positioned under the wearer's heel. - One embodiment of
air pump 130 comprises one-way valve 140. One-way valve 140 is adapted to allow air to enterair pump 130 throughinlet port 133 while preventing or reducing air flow out ofair pump 130 throughinlet port 133. In embodiments,inlet port 133 is at the back of the heel ofinsole 100. Referring toFIG. 2 , air expelled fromair pump 130 can pass throughairflow channels 150. -
Airflow channels 150 are adapted to direct air expelled fromair pump 130 toair holes 120. Air holes 120 can be distributed aroundfoot bed surface 110 to effectuate air circulation around the wearer's foot bed. In embodiments, air flow may prevent, mitigate, and/or eliminate foot odor, enhance the wearer's comfort, and/or effectuate temperature regulation. In embodiments,air holes 120 can be selectively placed aroundfoot bed surface 110 to optimize air flow and effectuate the desired benefits therefrom. For example, it may be desirable to increase air circulation around the wearer's toes. Air holes 120 may be placed around the toe area onfoot bed surface 110 while leaving fewer or no holes in the arch area onfoot bed surface 110, which may have the effect of increasing air circulation around the wearer's toes relative to aninsole having holes 120 dispersed around both the toe and arch areas. In various embodiments,air holes 120 may be selectively created with various spacing and diameters to result in desired air flow at optimal locations on the sole of the wearer's foot. - In one embodiment, each row of
air holes 120 are in fluid communication with oneairflow channel 150. In embodiments,airflow channels 150 are oriented from back to front along the bottom ofinsole 100. In some embodiments,airflow channels 150 comprise grooves in the bottom surface ofinsole 100. In other embodiments,airflow channels 150 comprise enclosed volumes embedded withininsole 100. In other embodiments,airflow channels 150 direct air flow in lateral directions withininsole 100. - In one embodiment, entering air may pass through
inlet 133 andvalve hole 145 intopump chamber 130.Valve hole 145 may be sized and/or shaped such that higher-than ambient air pressure withinpump chamber 130 causesvalve hole 145 to close or partially constrict, thus directing airflow forward throughchannels 150. Referring toFIGS. 3 and 4 ,inlet port 133 is positioned at the rear ofinsole 100. In embodiments whereinsole 100 is placed within footwear, such footwear may have a corresponding air flow hole at the rear of the footwear, through which air may pass before enteringinlet port 133 oninsole 100. In alternative embodiments,inlet port 133 is positioned at other areas of insole, such as a bottom surface, a side surface, a front surface, or a top surface. - Referring to
FIG. 5 , according to embodiments of the present disclosure,air pump 130 comprises a cavity that is open to the bottom ofinsole 100. Embodiments ofair pump 130 include a cavity having the shape of a spherical cap. Other embodiments ofair pump 130 include a cavity having a partial spheroid shape. Embodiments ofinsole 100 includeair channels 150 that are open to the bottom ofinsole 100.Insole 100 may be placed within footwear against the upper surface of the sole of said footwear. While thus placed within footwear, said upper surface of the footwear sole may act to partially or completely encloseair pump 130 and/orair channels 150. Referring toFIG. 6 ,air inlet 133 comprises an internal taper that terminates atvalve hole 145. According to embodiments, components ofvalve 140,air pump 130, andinlet 133 are formed from a unitary piece of a single material. - Embodiments of
insole 100 comprise arch support ridge 103 and toe ridge 105. Ridges 103, 105 may enhance the wearer's fit and/or comfort ofinsole 100. In various embodiments, the size and/or placement of ridges 103, 105, or other similar features may be created onfoot bed surface 110. In one embodiment, heel crease 107 comprises multiple folded layers of material, such as polyurethane, material, which may serve to provide increased elasticity and/or wearer comfort. - In various embodiments,
insole 100 is manufactured from polyurethane. Other embodiments are manufactured from various other suitable materials. Polyurethane used forinsole 100 may exhibit elasticity and/or shock-absorption qualities that may contribute to the wearer's comfort and/or to the effectiveness ofair pump 130. In one embodiment, theentire insole 100 is a unitary molded polyurethane component. In some embodiments,insole 100 is coated and/or otherwise covered with additional materials. Such additional materials may include moisture and/or odor absorbent materials. In other embodiments, a layer of padding material is adhered to footbed surface 110. - In operation, an insole according to the present disclosure may be inserted or placed within various forms of footwear. In other embodiments, an insole as set forth in the present disclosure is manufactured in and integrated with footwear. Insoles may be made for particular shoe sizes or shaped to fit particular types of footwear. In some cases, an insole may be trimmed prior to inserting into footwear to provide for an optimal fit. In some cases, prior to inserting the insole into a shoe, the original shoe insole may be removed from the shoe.
- As the wearer walks or runs, the wearer's gait may include a heel strike, a midfoot strike, and/or other types of foot strike. As pressure is applied by the wearer's foot to the insole during foot strike, the air pump can be compressed, thereby expelling air from the air pump cavity. The air may be forced through the channels and one or more outlet holes on the foot bed surface. In one embodiment, pressure from the wearer's foot onto the insole may result in a seal or a partial seal between lower surfaces of the insole and the upper (inside) facing surfaces of the footwear, such that air is directed to the air channels. Accordingly, embodiments of air pump cavity and/or air channels are open to the bottom of the insole but when the insole is placed within the footwear, the air pump cavity and/or air channels become enclosed or partially enclosed by the combined surfaces of the insole and the upper (inside) facing surfaces of the footwear.
- Under some circumstances, the air pump may not be compressed by the initial foot strike, but rather by pressure applied to the air pump cavity by later motions in the wearer's gait. In various embodiments, the placement of the air pump cavity may be selected to align to particular gaits and/or foot strikes.
- Although the present disclosure is described in terms of certain preferred embodiments, other embodiments will be apparent to those of ordinary skill in the art, given the benefit of this disclosure, including embodiments that do not provide all of the benefits and features set forth herein, which are also within the scope of this disclosure. It is to be understood that other embodiments may be utilized, without departing from the spirit and scope of the present disclosure.
