  • Custom orthotic sandal and process for constructing
    Patent number: 6523206
    Abstract: A custom orthotic sandal is formed to a biomechanically corrected shape of a user. To obtain the proper shape for the sandal, a negative cast is taken of the user's foot. A positive impression cast is then formed from the negative cast. The positive impression cast is then modified to correct for biomechanical abnormalities of the user's foot. The custom orthotic sandal is formed by adhering a moldable material on the sole of the sandal. The positive impression cast is then pressed on the moldable material to form the proper shape. The moldable material is then set and the sole is assembled into the sandal.
