Compared with the traditional EVA midsole, the E-TPU midsole is made of a physically foamed polyurethane material. It has a popcorn shape after molding. It has excellent resilience and deformation recovery, and its performance is far superior to that of traditional EVA materials. E-TPU materials are not only lightweight, but also retain their elasticity over a wide temperature range. Even under the freezing temperature of minus 20 °C, the foamed microspheres ensure that Energy Boost maintains excellent performance; the material has a rebound rate of 50-55%, and the compression set is low; the material properties are not sensitive to temperature changes and are soft. The perfect combination of touch and excellent elasticity.
