Shoe

Abstract

A shoe includes an upper attached to a sole, where the sole may include a footbed having an embedded internal frame and a midsole/outsole combination. The perimeter of the footbed is smaller than the perimeter of the midsole so that the portion of the footbed encompassing the internal frame may be inserted into the midsole. The upper of the shoe is inserted into a perimeter space formed between the footbed and the midsole whereupon the upper and midsole are secured together with fasteners, such as staples extending through the midsole and the upper, and into the internal frame.

What is claimed is: 
     
         1 . A shoe, comprising:
 a footbed having a footbed height, and a footbed perimeter with a curvature and dimension that corresponds to a foot of a wearer;   a midsole having a midsole height and midsole perimeter with a curvature and dimension that correspond to that of the footbed perimeter, wherein the midsole perimeter is larger than the footbed perimeter so that a lower portion of the footbed height is received in the midsole and provides a gap between the footbed perimeter and the midsole perimeter in a region where the midsole height overlaps the footbed height;   a upper for securing the shoe to the foot of the wearer, the upper having a lower edge received in said gap;   an internal frame in the footbed, the internal frame vertically positioned in a portion of the footbed height that is received in the midsole; and   a fastener extending horizontally through the midsole and into the lower edge of the upper and the internal frame.   
     
     
         2 . The shoe of  claim 1 , wherein fastener comprises a plurality of fasteners, and wherein the fasteners comprise staples. 
     
     
         3 . The shoe of  claim 2 , further comprising:
 a cover enclosing an upper surface and sides of the footbed so that the plurality of fasteners pass through the cover before entering the internal frame.   
     
     
         4 . The shoe of  claim 1 , wherein the footbed height extends between an upper surface in contact with the foot of the wearer and a lower surface, and the footbed further comprises at least one channel in the lower surface for receiving the internal frame. 
     
     
         5 . The shoe of  claim 4 , wherein the internal frame extends around an entirety of the footbed perimeter. 
     
     
         6 . The shoe of  claim 4 , wherein the internal frame comprises a lateral frame and a medial frame that extend longitudinally along a respective side of the footbed. 
     
     
         7 . The shoe of  claim 4 , wherein the internal frame is rigid material. 
     
     
         8 . The shoe of  claim 7 , wherein the rigid material is thermoplastic polyurethane (TPU). 
     
     
         9 . The shoe of  claim 1 , wherein the midsole height varies around the midsole perimeter. 
     
     
         10 . The shoe of  claim 1 , wherein the midsole is a lightweight polymer. 
     
     
         11 . The shoe of  claim 10 , wherein the lightweight polymer is molded ethylene vinyl acetate (EVA). 
     
     
         12 . The shoe of  claim 1 , further comprising an outsole secured to the midsole opposite the footbed.
