One of the appealing aspects of NIKE SHOX technology is its ability to be tuned to specific sports and even the needs of specific athletes. Its prospects are exciting. Attached to the SHOX cylinder is a TPU (thermoplastic urethane rubber) heel that provides support for the heel while the SHOX cylinder disperses the impact. SHOX replaces real springs with high-density PU foam columns. It absorbs the energy of the impact and converts it into kinetic energy. The slip resistance of SHOX shoes is very good, because the strong SHOX air column is placed at the outer edge of the outsole. According to the principle of the lever, the moment of the side impact force = the moment of the force at the connection of the air column, but the force at the joint The arm is long, so the force is small, so that the side slip does not drag the water.
