Moisture and temperature regulating insole

An insole for a shoe, the insole comprising:

• an air permeable hydrophilic absorbent layer;
• a resilient elastic layer adjacent the absorbent layer, the elastic layer capable of expansion to absorb air and compression to release the absorbed air;
• and
• an air permeable closure layer adjacent the elastic layer, the closure layer allowing the transfer of gases therethrough and preventing the passage of fluid therethrough.

A shoe comprising:

• a body having a cover and a base layer connected to the cover, the base layer used to support a foot;
• a sole having a base connected to the body and an expansive foam between the body and the base;
• and
• an insole between the body and the sole, the insole including an absorbent layer;
• an elastic layer, and a closure layer, wherein the insole absorbs the moist air within the shoe during an advance phase of the foot when the shoe is detached from the ground or floor and delivers the absorbed air with a lower content of moisture and temperature during the support phase of the foot when the shoe is supported on the ground or floor, in part to the environment and in part to the shoe body.
