Three materials – shock-absorbing ethylene vinyl acetate (EVA) in the middle heel, an energy storage system (ESS) material below the EVA, and a thermoplastic polyurethane (TPU) window in the outsole – create a stage-by-stage shock-absorption process. During landing, the impact force on the heel is absorbed by the EVA and ESS materials through deformation; the enclosed air pressure and the ESS material then work to reverse the deformation quickly, bringing the material back to its original state and applying vertical force. These materials improve the heel’s shock absorption, as well as the support provided by the insole.
