ABSTRACT:
An insole for a shoe, and method of manufacture, comprises a bottom layer formed of cushioning material, and a top layer formed with apertures, which, in various methods of manufacture, is embedded into the bottom layer so that the cushioning material forming the bottom layer extends at least partially into the apertures in the top layer. The coefficient of friction of the top layer of the insole which contacts the foot of the wearer is variable and chosen to control the movement of the foot along the insole depending upon the type of activity and playing surface for which the shoe is designed.
