Abstract
An affixable pad for corns, calluses, bunions, and the like, made from a soft viscoelastic gel material. Preferably, the gel contains a high percentage of plasticizing oil such as Mineral Oil U.S.P. The gel is impregnated onto an elastic fabric, such as Spandex, which allows the gel to flow around a lesion and equalize pressure in a superior manner.
