Descente Genten - for racing Color: Blue Used once each for road races and track races. I quickly outgrew them, so I'm now using the same shoe in 26cm, which I liked so much. They are very light. Feel free to ask any questions. GENTEN RC for racing, 25.5cm New retail price: 15,400 yen The following is the description: [Shoes usable for track events of 800m or more] Running shoes for serious runners seeking "speed," pursuing the "GENTEN (origin)" of running. From the last designed for runners, which focuses on converting the force of kicking the ground into propulsion without waste, it achieves a fit that minimizes the loss of leg power. The drop created by the unique sole shape achieves both propulsion and stability. The thin sole x high-rebound sole generates a rebound force that connects the force of kicking the ground to the next step. "Graphene," a Nobel Prize-winning material, is blended into the outsole rubber.
