This C10 PRO II is designed for elite marathons and long-distance races. It combines a unique split-toe forefoot propulsion system with a lattice system to achieve extreme propulsion and precise control. The design of the shoe is inspired by the dynamic posture of hunting sharks, and the asymmetrical streamlined design reflects the forward posture of "ready to attack at any time. This design functionally maintains the runner's high center of gravity, enhances the pedaling response, and perfectly releases the power of the sole to increase the maximum speed, while visually strengthening the competitive mentality.
