LI - NING CLOUD LI - NING CLOUD brand new damping technology, full use palm bottom LI NING polymer materials formula, the impact of the effective damping when the accumulation. And translated into the springback energy, form efficient energy cycle system. BOUNSE/recovery technology Bounse is a kind of high resilience to the shock of EVA material, while provides the user with a good comfort, when can reduce the movement of the stretching loss of energy. As/cushioning technology As is a kind of high damping function of the foaming materials, the main buffer parts used in shoe bottom, in the process of movement, foot CUSHION, can smooth the excesses and proper support. Tick the instep: cow split leather + fabric Tick sole: rubber + EVA + TPU + carbon fiber composite
