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.

A disposable insert for footwear comprised of a top surface and a bottom surface. The top and bottom surfaces are substantially thin and made of PP spunbonded nonwoven materials to keep a wearer's foot clean by absorbing sweat, odor and dirt. The top surface has a high coefficient of friction to provide good traction to the bottom of the wearer's foot during wear, especially for those individuals whose feet tend to sweat often while wearing shoes. The bottom surface has an anti-slip adhesive coating for allowing the insert to adequately grip the insole of a shoe without leaving a residue that could damage the wearer's shoe when removed, yet easily moveable in shoes as necessary. The present invention also provides a disposable insert composed of different colors and patterns to satisfy the fashionable preferences of the wearers.

A multi-ply shockproof, hygroscopic and breathable shoe pad includes, from bottom to top in succession: a support bottom layer (1), wherein a lower end face of the support bottom layer (1) is provided with a plurality of protruding portions (5), an upper end face of the support bottom layer (1) is provided with air holes (6), and the protruding portions (5) and the air holes (6) are alternately arranged; an elastic interlayer (2), wherein the elastic interlayer (2) is provided with air holes (6), and is coated with an antibacterial deodorization layer; a hygroscopic interlayer (3), wherein the hygroscopic interlayer (3) is provided with air holes (6), and is coated with an antibacterial deodorization layer; and a breathable waterproof layer (4) coated with an antibacterial deodorization layer; and the support bottom layer (1), the elastic interlayer (2), the hygroscopic interlayer (3), and the breathable waterproof layer (4) are successively bonded.

Disclosed are shoes including a body having a foot insertion space into which user's foot is inserted, an air passage portion protruding from a front of the body to the outside and extending in a direction in which the body extends, and a foot support portion located in a width direction of the air passage portion. In addition, shoes according to another feature includes a first body portion in which a portion of a front foot portion of a wearer is positioned, a second body portion connected to the first body portion and in which the other remaining portion of the front foot portion, a middle foot portion, and a rear foot portion of the wearer are positioned, a cover seamlessly connected to the second body portion and protruding in an outward direction from both edge portions, at least one protrusion protruding from an inner surface of the cover and extending in a direction in which the second body portion extends, wherein a protruding thickness of each protrusion decreases from an upper portion toward the first body portion.

An insole includes an insole body made of a breathable foam material, a fabric layer unit bonded to the insole body along a stacking axis, and a plurality of air holes. The insole body has a bottom surface, a top surface, and a plurality of air voids spatially interconnected and capable of connecting to the bottom surface and the top surface. The fabric layer unit includes a fabric layer and a waterproof membrane. The waterproof membrane is disposed between the fabric layer and the insole body, and is bonded to the top surface of the insole body. The air holes are connected to the fabric layer and the waterproof membrane. The air holes and the air voids are spatially interconnected. Each of the air holes has a hole width of less than 0.1 mm. The air holes and the air voids together form a plurality of air channels.

An article of footwear includes a sole having a bottom surface configured to contact ground when the article is worn by a wearer, a top surface opposite the bottom surface, and an inwardly directed rim extending about at least a portion of a periphery of the sole. The rim defines a channel sized to receive a peripheral edge of an insole for retaining the insole over the top surface of the sole. The article also includes an upper attached to the sole defining an opening sized to receive a foot of a wearer, the upper being configured to secure the sole to the wearers' foot.

An ultraviolet (UV) footwear illuminator for footwear treatment is disclosed. In one embodiment, the UV footwear illuminator includes an insert adapted for placement in an article of footwear. At least one UV radiation source is located in the insert and is configured to emit UV radiation in the footwear through a transparent window region formed in the insert. A control unit is configured to control at least one predetermined UV radiation characteristics associated with the radiation emitted from each UV radiation source. A power supply is configured to power each UV radiation source and the control unit.

Reduction of body odors arising from microbial activity in moist areas of the human body, particularly the foot area, is achieved by providing a substrate that is treated with an amphoteric metal compound solution, especially those containing copper, which provides a stable material that can be placed in proximity to a part of the body that typically develops body odor, the treated material providing extended efficacy in the prevention of odor caused by microorganisms despite continuous and repeated exposure of the treated substrate to sweat or laundering.
