Abstract

An insole which generates an air flow during use, which assists in cooling or warming the foot of a user is disclosed. In a first embodiment, air flow facilitated by said insole provides for convective heat transfer away from the plantar surface of the foot. The insole is intended for insertion into a shoe which is ventilated, preferably an athletic shoe with a ventilated upper. The bottom layer defines a plurality of ridges and channel lining portions which together define a plurality of air channels. The bottom layer defines a heel recess in which a heel pad is situated. In a second embodiment, an insole which collects, retains, and heats a user's foot is disclosed. Said insole further comprises a middle layer of thermal reflective material secured to and coextensive with a top layer and a bottom layer secured to said middle layer.

Dependent claims

An insole comprising:

a bottom layer having a top side and a bottom side, a heel portion, a toe portion and an arch portion;
a heel pad positioned in a heel recess area in said heel portion on said bottom side of said bottom layer;
a plurality of curvilinear ridges located on bottom side of by the bottom layer and protrude outwardly from the bottom side of said bottom layer and extend essentially lengthwise along a longitudinal insole axis that extends longitudinally from the heel portion into the toe portion, said plurality of longitudinal curvilinear ridges occupy substantially the lateral width of the bottom side of said insole bottom layer;
one or more channels positioned between said curvilinear ridges and extending essentially lengthwise along said longitudinal insole axis extending essentially longitudinally from the heel portion into the toe portion in parallel with one or more of said curvilinear ridge;
a portion of one or more of said plurality of curvilinear ridges adapted to make contact with the bottom internal surface of a user's shoe, said channels forming a plurality of air channels to force air flow along an air pathway positioned in one or more of said channels;
one or more elongated recesses located on said bottom layer, said one or more elongated recesses being positioned within one or more of said channels and occupying a portion of the longitudinal length of said one or more channels;
said heel pad having inside heel ridges that each protrude outwardly from the surface of the heel pad occupying substantially the lateral width of the heel pad and having heel channels defined by the space between said heel ridges, wherein said heel ridges and heel channels extend essentially lengthwise along a longitudinal heel axis and extend essentially parallel to said longitudinal axis of said bottom layer, said heel ridges being adjacent to said curvilinear ridges of said bottom layer such that heel channels are in communication with adjacent channels in said bottom layer of said insole and assist air flow along the bottom layer.

one or more channels positioned between curvilinear ridges and extending essentially lengthwise along said longitudinal insole axis and extending essentially longitudinally from the heel portion into the toe portion in parallel with one or more of said curvilinear ridges,
a portion of one or more of said plurality of curvilinear ridges adapted to make contact with the bottom internal surface of a user's shoe, said channels forming a plurality of air channels to force air flow along said plurality of air channels forming an air pathway positioned in one or more of said channels;
and
said heel portion having inside heel ridges that each protrude outwardly from the bottom surface of the bottom layer of the heel portion and extend essentially lengthwise along a longitudinal heel axis that extends essentially parallel to said longitudinal axis of said bottom layer.
