Ventilated and resilient shoe apparatus and system

Abstract

An improved shoe includes an apparatus and system for ventilating inside the shoe and a resilient shoe. External air desirably enters the shoe around the wearer's foot and flows through holes in the sole into aeration chambers. The air circulates to the heel by a suction valve and is controllably directed out to the exterior of the shoe through a one-air air exhaust valve, ventilating the wearer's foot while an individual is walking. The heel is made from a resilient material and has a cavity extending under the entire instep portion of the shoe's upper. Compression springs are placed in the cavity, including a mainspring located at approximately the heelstrike point and two auxiliary springs for stability located forward of the mainspring toward the shoe's toe. The action of the springs is distributed throughout the sole by a resilient layer of softer rubber adjacent the sole to provide for a resilient walking experience.

1 . A shoe having a longitudinal shoe axis, comprising:
 a lower having an upper sole extending the length of the shoe, including a heel portion, an instep portion, and a toe portion, and said lower including a blended heel extending under said instep portion of said upper sole;   a cavity in said blended heel extending under said instep portion of said upper sole toward said toe portion; and   a plurality of springs within said cavity, said springs being oriented generally orthogonal to said shoe axis.   
     
     
         2 . The shoe of  claim 1  wherein said lower, including said blended heel, is made of resilient material to cushion the steps of the wearer. 
     
     
         3 . The shoe of  claim 2  wherein there are two separate resilient materials comprising the heel, the top material being softer than the remainder. 
     
     
         4 . The shoe of  claim 2  wherein said cavity tapers from a relatively large area at the heel of the shoe to a point under the toe portion of said sole. 
     
     
         5 . The shoe of  claim 4  wherein there are three springs in the cavity, and said three springs comprise a mainspring located so as to align with the point of heelstrike on the sole and at least one auxiliary spring located forward of the mainspring. 
     
     
         6 . The shoe of  claim 5  wherein said mainspring is secured into said cavity by lugs at either end of the spring, said lugs are formed in recesses extending above and below said cavity. 
     
     
         7 . The shoe of  claim 5  wherein two auxiliary springs are located forward of said mainspring, the mainspring is located on the longitudinal axis, and the two auxiliary springs are located on either side of said longitudinal axis, and said auxiliary springs are located about equidistant from both the mainspring and said longitudinal axis. 
     
     
         8 . A ventilated shoe comprising
 a lower with an upper sole having a plurality of openings therein, said lower having aeration channels and at least one air suction channel adjacent to said aeration channels;   a heel portion having a cavity with a volume therein, said heel portion adjacent to said at least one air suction channel, said cavity in communication with a one-way exhaust valve in communication with the exterior of the shoe to expel air from the cavity,   wherein the shoe is adapted to provide that air flows into the shoe through the upper sole to said aeration channels through said at least one air suction channel to said cavity and is expelled outside of the shoe through said one-way exhaust valve by reduction of the volume of the cavity.   
     
     
         9 . The ventilated shoe of  claim 8  further comprising an air pump within said cavity having a one-way air suction valve for intake of air from said at least one air suction channel, said air pump configured to expel air through said one-way exhaust valve upon the compression of said air pump. 
     
     
         10 . The ventilated shoe of  claim 8  further comprising a second sole placed between said upper sole and said aeration chambers, said second sole being air permeable. 
     
     
         11 . A system for ventilating a shoe comprising:
 a lower having an upper sole with a plurality of openings therein, said lower having air flow structures therein in communication with said upper sole;   a heel portion having an air pump therein, said air pump having an air suction valve in communication with said air flow structures, said air pump also in communication with an exhaust valve, said exhaust valve in communication with the exterior of the shoe to expel air from said air pump, said air pump configured to intake air from said air suction valve when expanded and to expel air to said exhaust valve when compressed; and   whereby the shoe is adapted to provide that air enters the shoe and flows through the upper sole to said air flow structures to said air suction valve and is expelled outside of the shoe through said one-way exhaust valve by operation of said air pump.   
     
     
         12 . The system for ventilating a shoe of  claim 11  further comprising a water proof ventilation valve on the exterior of the shoe and in communication with said exhaust valve. 
     
     
         13 . The system for ventilating a shoe of  claim 11  further comprising a second sole placed between said upper sole and said aeration chambers, said second sole made from air permeable material. 
     
     
         14 . A combination resilient and ventilated shoe comprising:
 a lower having an upper sole with a plurality of openings therein and air flow structures therein in communication with said upper sole and extending the length of the shoe into a heel portion,   a cavity in said heel portion and at least one spring member within said cavity, said cavity having a one-way exhaust valve in communication with the exterior of the shoe to expel air from the cavity;   wherein the shoe is adapted to provide that air enters the shoe and flows through the upper sole to said cavity in the heel and is expelled outside of the shoe through said one-way exhaust valve by reduction of the volume of the cavity.   
     
     
         15 . The combination resilient and ventilated shoe of  claim 14  further comprising an air pump within said heel cavity, said air pump configured to expel air through said one-way exhaust valve upon the compression of said air pump. 
     
     
         16 . The combination resilient and ventilated shoe of  claim 14  further comprising permanently magnetic material disposed in the lower. 
     
     
         17 . The ventilated shoe of  claim 14  further comprising a second sole placed between said upper sole and said aeration chambers, said second sole being air permeable. 
     
     
         18 . The combination resilient and ventilated shoe of  claim 17  further comprising a thermoelectric cooling device in the lower to remove heat and humidity from said second sole.
