An footwear cushioning system comprising a matrix of elongate, hollow, elastomer tubes joined together in a honeycomb matrix which extends laterally at least partially across selected portions of the sole of the footwear. The tubes may or may not be enclosed in an air bag.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A footwear cushioning system comprising:
 (a) a matrix of hollow elastomeric tubes which extends at least partially across the lateral extent of a sole of the footwear.   
     
     
         2 . A footwear cushioning system of  claim 1  wherein said tubes are attached to one another. 
     
     
         3 . The footwear cushioning system of  claim 1  wherein said tubes are circular in cross-section. 
     
     
         4 . The footwear cushioning system of  claim 1  wherein said tubes are polygonal in cross-section. 
     
     
         5 . The footwear cushioning system of  claim 4  wherein said tubes are hexagonal in cross-section. 
     
     
         6 . The footwear cushioning system of  claim 1  wherein said tubes are made from a thermoplastic olefin. 
     
     
         7 . The footwear cushioning system of  claim 1  wherein said tubes made from a thermoplastic elastomer. 
     
     
         8 . The footwear cushioning system of  claim 1  wherein said tubes are located in a toe portion of the footwear. 
     
     
         9 . The footwear cushioning system of  claim 1  wherein said tubes are located in a heel portion of the footwear. 
     
     
         10 . The footwear cushioning system of  claim 1  wherein said tubes are located in both a heel and the portions of the footwear. 
     
     
         11 . The footwear cushioning system of  claim 1  wherein said tubes are located within a sealed air bag. 
     
     
         12 . The footwear cushioning system of  claim 10  wherein the air in said bag is at an elevated pressure. 
     
     
         13 . The footwear cushioning system of  claim 1  wherein said tubes have a cross-sectional size which can vary depending on the application. 
     
     
         14 . The footwear cushioning system of  claim 1  wherein said tubes have a wall thickness which can vary depending on the application.
