Abstract
A sole supporting and cushioning member for footwear controlling the movement of foot/leg muscles in the form of a removable, preferably disposable sole shock absorber that is adapted to afford an elastic or cushioned bearing for the wearer's feet which comprises a pliable coil filled with an elastomeric material to resiliently flex with the movement of the sole of the foot.
Claims11
An insert for covering at least a part of the sole position of footwear comprising:
- a pad portion,
- said pad portion comprising a relatively flat sole engageable member having a circular aperture therein,
- a resilient tubular member secured within said aperture in said flat sole engageable member in a coiled configuration substantially flush with the flat engaging surface of said sole engaging member,
- said tubular member comprises a hollow configuration filled with a fluid material and
- means for anchoring the pad to the sole portion of the footwear used,
- whereby when the sole of a user is applied to said tubular member, it momentarily distorts under its pressure and returns to its initial position when the force is changed thereby serving as a shock and torque absorber for the footwear.
