The CloudTec sole uses a two-layered Helion super foam with different densities to provide the highest level of cushioning. The upper layer of foam, which is placed thickly around the foot, maintains high resilience, while the lower layer of foam provides softer cushioning and shock absorption. In addition, it is equipped with a Speedboard made of a nylon mix that is lighter and more resilient than the previous model, and the upper is made of engineered mesh made of 100% recycled polyester, providing the wearer with a stress-free and comfortable fit.
