Abstract
A removable insert for footwear has a slot placed in its medial edge which extends below the arch. An insert placed into the slot has a height which establishes how much the arch protrudes above the remainder of the top surface of the insole. Multiple inserts are provided having different thicknesses so that the height of the arch can be varied.
