Abstract
Internal pads of sponge material are preferably enclosed in a fabric casing and secured to the inside surface of rubber boots or shoes. The construction permits the wearer to put his feet into the boots without strenuous effort. Also, the boots may be removed easily without using a zipper opening or shoe laces. While being worn, the wearer may run or take long walking steps without fear of losing the boots or of displacing the foot within the boot. The sponge inserts hold the foot in its proper place by forcing the foot into contact with the inner sole.
