An orthotic device is disclosed. The orthotic device may be adapted to be inserted into a shoe to enable the foot to replicate normal motion so that the user regains substantially normal operation of the foot. The orthotic device may have a frame system formed of a lightweight supportive material and configured to extend along at least the bottom of the user's foot, and an electronically actuated muscle operatively connected to the frame system for expanding and contracting at predetermined levels to adjust the inclination of the user's foot and mimic movement of the foot, when functioning normally. The orthotic device may also have a controller operatively connected to the muscle for transmitting signals corresponding to the predetermined levels to the muscle, and a sensor controlled by the user for actuating the muscle.
