Nike KO Boxing Shoe - Game Royal/White - TRAIN HARD. HIT HARDER - Lightweight and durable foam mesh upper with abrasion resistance on the toe. The midsole is constructed with strong light weight materials to maximize speed and stability in the ring. OUTSOLE: A sold punch starts with solid footwear. Because of this, we improved the shoe's feel for the floor and traction with reengineered gum rubber soles that are thinner and more sticky.
