Patent number: 4619056Abstract: An insole (10) for disposal in a shoe adjacent the sole of the foot includes a cushioning layer (12) having one surface thereof for disposal adjacent the sole of the foot and having a profile around the perimeter thereof which generally conforms to the contour of the sole of the foot to better disperse forces thereabout. The cushioning layer (12) includes a heel portion (14), a mid portion (16) and a toe portion (18). A plurality of arcuate ridges (20) are disposed on the surface of mid portion (16) and are integrally formed therewith. Ridges (20) are disposed in spaced apart relationship on the surface of mid portion (16) and extend across the entire width of insole (10) to form arcs of concentric circles having their radial centers in the middle of the heel portion (14). Each of ridges (20) is triangular in shape with its apex located adjacent the arch of the foot. Ridges (20) are thus operative to create a raised portion (26) on the upper surface of insole (10) adjacent the arch of the foot.Type: GrantFiled: March 28, 1985Date of Patent: October 28, 1986Assignee: Autry Industries, Inc.Inventors: Mark Y.
