Abstract
A removable insole is provided which includes a layer of thermoplastic material, the thermoplastic material preferably including ethylene vinyl acetate and ethylene vinyl acetate modified by the addition of carbonyl groups. A custom-fitting insole is preferably produced by heating a substantially flat insole in a microwave oven until the thermoplastic material softens, placing the heated insole in a shoe, and having a person insert their foot into the shoe and walk around to form an impression.
