I ran 1 kilometer in these. I'm selling them because they don't fit my feet. Original price: 18,700 yen (tax included) Size: 25cm These are racing shoes for runners aiming for a full marathon time of 3 hours to 3 hours 30 minutes, significantly evolved from the previous model. Recommended pace is around 3 minutes 30 seconds to 5 minutes per kilometer. This model incorporates Mizuno's unique speed technology, "Smooth Speed Technology." It guides the runner towards an efficient running motion similar to forefoot running, making it less likely to fatigue the muscles around the calves, thus assisting in achieving the target. The midsole has a three-layer structure, sandwiching a nylon plate reinforced with glass fiber between two layers of foam material, providing easy wear, high cushioning, rebound, and stability. MIZUNO ENERZY LITE+, also used in Wave Rebellion Pro 2, is used in the top midsole closest to the foot, providing a soft feel. MIZUNO ENERZY foam is used in the bottom midsole, offering a more comfortable feel compared to Wave Rebellion Pro 2. The outsole is also made of rubber, providing a natural and soft ground contact feel. The upper, which uses a racing last, also features an inner strap to reduce foot wobble during high-speed running.
