Cushioned Sole with Air Chamber and Resistance Protrusions

Abstract

A shoe providing increased comfort and decreased weight without sacrificing in quality or durability by cresting a chamber below the insole, and preferably in between an outsole and a midsole, with protrusions projecting up from the outsole towards the chamber directly beneath the midsole. In some embodiments, the protrusions may project directly into the chamber but maintains a gap between the top of the protrusions and the midsole.

What is claimed is: 
     
         1 . A shoe, comprising:
 a. an outsole;   b. a midsole positioned above the outsole, wherein the midsole is feed to the outsole;   c. a chamber in between the outsole and the midsole, wherein the chamber extends from a front portion of the shoe to a heel portion of the shoe;   d. a plurality of protrusions projecting up from the outsole into the chamber directly beneath the midsole, wherein the protrusions are characterized by a rounded top portion and a base opposite the top portion, the base integrally formed with the outsole, wherein the top portion of each protrusion and the midsole define a gap therebetween when in a natural state; and   e. an arch support within the chamber in between the front portion and the heel portion, wherein the arch support is a rigid sheet having a convex top surface and a concave bottom surface.   
     
     
         2 . The shoe of  claim 1 , wherein the air chamber comprises a heel chamber section and a metatarsal chamber section. 
     
     
         3 . The shoe of  claim 2 , wherein the heel chamber section and the metatarsal chamber section are sealed from each other. 
     
     
         4 . The shoe of  claim 1 , wherein the air chamber  108 ,  110  is lined with an airtight lining. 
     
     
         5 . A shoe, comprising:
 a. an outsole;   b. a midsole positioned above the outsole;   c. an insole positioned above the midsole;   d. a chamber below the insole, wherein the chamber extends from a front portion of the shoe to a heel portion of the shoe; and   e. a plurality of protrusions projecting up towards the insole, wherein the protrusions are characterized by a rounded top portion and a base opposite the top portion, the base formed adjacent the outsole, wherein the top portion of each protrusion and the insole define a gap therebetween when in a natural state.   
     
     
         6 . The shoe of  claim 5 , wherein the chamber comprises a heel chamber and a metatarsal chamber. 
     
     
         7 . The shoe of  claim 6 , wherein the two air chambers are sealed from each other. 
     
     
         8 . The shoe of  claim 5 , wherein the air chamber is lined with an airtight lining. 
     
     
         9 . The shoe of  claim 5 , wherein the midsole is a sealed bladder having a top side and a bottom side with the air chamber defined by the top and bottom side of the midsole. 
     
     
         10 . The shoe of  claim 9 , wherein the protrusions are Integrally formed with the outsole and abut the bottom side of the midsole. 
     
     
         11 . The shoe of  claim 5 , further comprising an arch support in between the front portion and the heel portion, wherein the arch support is a rigid sheet having a convex top surface and a concave bottom surface. 
     
     
         12 . The shoe of  claim 5 , wherein the protrusions are integrally formed with the outsole and protrude into the chamber beneath the midsole, wherein the top portion of each protrusion and the midsole define the gap.
