Nike HyperKO Limited Edition - White/Metallic Gold - Keeping the Nike HyperKO strong and light are Nike Flywire supports – high-strength threads that work like cables on a suspension bridge with support engineered precisely where the athlete needs it while boxing.To account for the tremendous torque applied by boxers while punching, a lockdown strap has been placed in the forefoot area.This support system allows the Nike HyperKO to be constructed with a substantial amount of mesh which minimizes weight, and helps with ventilation and moisture management.
