Abstract: Provided herein are mid-soles, sole assemblies, footwear inserts and articles of footwear for walking and running. The midsoles include three cushioning members where the height of the midsole provides a zero drop elevation. The midsole architecture provides dynamic variable resistance that improves performance by using different densities and angles of component mid-sole members that will allow the wearer to move through a full range of motion during walking or running with muscle effort remaining constant while shifting the workload from muscles that have limited power in certain positions, to those with more explosive and endurance capabilities in those same positions.
