ABSTRACT:
A torsional spring insole for use in footwear having an elevated heel section for supporting the heel of a foot and an inner sole in communication with the elevated heel section for providing a torsional spring capability to the insole. A step-down region is provided for connecting the elevated heel section to the inner sole for flexing the inner sole in response to a pressure imbalance applied to the elevated heel section. The inner sole subsequently reflexes with the movement of the foot to position the elevated heel section to eliminate the pressure imbalance and to counteract pronation and supination in the foot.
The elevated heel section of the insole employs the heel counter structure of the shoe in which the insole is inserted to assist in counteracting pressure imbalances associated with pronation and supination. In an alternative embodiment, the elevated heel section of the insole includes a vertical heel counter for counteracting pressure imbalances due to pronation and supination.
