Abstract: A replaceable tuning wedge-shaped piece of a variety of hardnesses, is inserted in the midsole of shoes for enhancing the rate of compression. As the shoe breaks down or compresses, the tuning wedges will help the midsole rate of compression in each individual's gait. Such wedges can be made of elastomers, rubbers, plastics, wood, air bladders, Skydex brand thermoplastic polyurethane (TPU) material, D3O® Set Foam, or the like. A method of adjusting the density and compression of the midsoles or platforms of footwear includes using these wedges in shoes. An athletic or casual or dress shoe can include an upper component, a midsole, an outsole, and a void or voids along the midsole borders for housing wedges of different durometers for controlling compression rates of each foot of the individual wearer.
