Flexy Ground boots are designed to enhance the performance of any shoe. Made from an innovative, patented elastic material, the Flexy Ground system combines the amazing performance and comfort of an insole with the responsiveness and versatility of an outsole. The result is an incredible improvement in both comfort and performance in any walking or running shoe. Increased ankle support and flexibility are provided by the outsole while reducing upper body weight while maintaining full-sized foot support on all four sides of the boot.
