COOL SHELL
As a temperature-control technology, COOL SHELL solves the problem of rising foot temperature during exercise comprehensively. By forming a special breathable and temperature-controlling system with Ice Fiber to control the temperature around collar and tongue part and functioning structure to increase the speed of air flow in shoe upper and sole, the integral temperature inside the shoe can be decreased efficiently. As tested by SGS, this COOL SHELL with Ice Fiber is of 80% more in temperature reduction compared with other shoe materials.
