A midsole comprises a heel cup having a semi-rigid upper plate, a lower plate composed of a material that is softer than the upper plate, and at least one telescopic shock absorber between the upper and lower plates. The telescopic shock absorbers have one portion that collapses into a second portion when the shock absorber is loaded or compressed. On release of the load, the shock absorbers of the invention return only a controlled portion of the compressive load originally applied. A second embodiment has a translucent heel cup and shock absorbers and a lamp for illuminating the heel cup and shock absorbers.

1. A midsole for footwear comprising,a semi-rigid upper plate; a lower plate, said lower plate composed of a material that is softer than said upper plate; and at least one shock absorber between said upper plate and said lower plate, said shock absorber being telescopic whereby compression causes one portion of said shock absorber to retract within a second portion of said shock absorber, said shock absorber comprising means for returning a force in response to an applied load, said return force being a minor portion of said applied load.
