My response to the statement made by Dr. Hirsch is more one of common sense.

How would a 1/4 inch gel cushion, which provides no stability whatsoever, possibly deliver the equal heel strike absorption and cushioning as an engineered tempered steel coil that is attached to a rigid orthotic built into the Z-Coil footwear.

Dr. Hirsch obviously has little experience with Z-Coil footwear.
