Insole-ventilating shoe

Claim 1

An insole-ventilating shoe comprising: a shoe having a waist ventilating hole formed on a waist portion of a vamp and a front ventilating hole formed on a toe cap; and an insole having a front portion formed with plural ventilating grooves underneath said front portion of said insole and a rear portion formed with an air pumping means thereon, said plural ventilating grooves fluidically communicated with said air pumping means; the improvement which comprises: said air pumping means preferably made of elastic material integratedly formed with said insole including: an upper arcuate film concave downwardly, a flat bottom film circumferentially formed with a lowest periphery of said upper film, a longitudinal slot formed on a central portion of said bottom film as snugly sealed by a sole inside said shoe under said insole, an air guide extension protruding upwardly from a waist portion of said insole having a generally vertical ventilating groove formed on said air guide extension to fluidically communicate with said waist ventilating hole on said vamp, a recess formed on said air guide extension as communicated with said vertical ventilating groove and filled with a filter preferably impregnated with refreshing agents or perfumes, an air intake valve formed on said vertical groove and communicated with a pumping chamber defined between said upper film, said bottom film and said sole sealing said longitudinal slot of said bottom film, and an air exhaust valve formed between said pumping chamber and said ventilating grooves formed on said front portion; and said plural ventilating grooves including: plural intermediate ventilating grooves formed underneath said front portion having each groove protruded expansively to its middle portion and then contractively to its front portion to define a generally elliptic contour between said pumping chamber and a toe portion of said insole, plural longitudinal ventilating grooves formed underneath said toe portion fluidically communicated with said intermediate ventilating grooves, plural arcuate ventilating grooves each generally parallel to an arcuate edge of the toe portion and the front portion of said insole and centrally intersecting with one said longitudinal ventilating groove, and plural perforations distributively formed in said ventilating grooves through said thickness of said insole, whereby upon the stepping of said shoe on a ground, the air in said pumping chamber will be compressed to flow through said exhaust valve, said ventilating grooves and said perforations for comforting a wearer's foot, and upon the lifting of said shoe from the ground, the environmental fresh air will be sucked through said waist ventilating hole into said pumping chamber as filtered by said filter in said recess of said pumping means.
