A SOLID PUNCH STARTS WITH SOLID FOOTWEAR. UPPER: Lightweight and durable foam mesh upper with abrasion resistance on the toe. MIDSOLE: The midsole is constructed with strong light weight materials to maximize speed and stability in the ring. OUTSOLE: A solId 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.
