Abstract

A low friction shoe insert of ultrahigh molecular weight polyethylene or the like having a coefficient of friction of 0.3 or less with an array of detachable discrete cushion elements on the shoe contacting lower surface to both frictionally anchor the insert to the shoe and permit the shape to be customized to the wearers foot and selectively relieve pressure on painful and sensitive areas.

Claims

1. A shoe insert comprising in combination:

a thin sheet of low friction plastic shaped to fit over the bottom inside surface of a shoe, so as to be positioned between the shoe bottom and a foot in the shoe, said thin sheet having a top, foot contacting, low friction surface and a bottom, shoe facing, surface;

a measurement scale on said bottom surface extending generally from the toe end of the insert to the heel end of the insert;

strips of loop and hook fabric type fastening material, also extending generally from the toe end of the insert to the heel end of the insert, said strips positioned adjacent the sides of said scale;

a plurality of generally rectangular detachable and replaceable cushion pad elements having hook and loop fabric type fastening material thereon, said pads being of varying thickness so that they can be mounted across said strips, in locations determined by said scale, so as to permit the thickness and shape of the insert to be adapted to the users foot.
