ABSTRACT:
An insert, particularly for athletic shoes, is removably fitted over or affixed atop the top surface of the insole of the shoe and comprises a thin section of non-absorbant, thermally non-conductive thermoplastic material which is deformable to conform to the shape of the insole. The insert is formed with a plurality of spaced apertures to permit the passage of air and moisture between the sock and insole. The coefficient of friction of the uppermost surface of the insert is approximately equal to that of the skin of the foot so that movement of the foot and sock within the shoe is limited to reduce the incidence of turf toe, while permitting at least some motion of the foot and sock within the shoe especially during sudden stops or starts to avoid blistering of the foot.
