Unused YONEX SAFERUN 100X WOMEN'S Running Shoes 23 These are YONEX WOMEN'S running shoes purchased at a sports store. Unused, with tags. Retail price: 18,700 yen Description: Equipped with the unique material "Power Cushion Plus" inside the sole. While maintaining the conventional lightness, this shock-absorbing and rebounding material increases shock absorption by 28% and rebound by 62% compared to the general shock absorber EVA, mitigating the impact during running and protecting the knees. The upper layer of the midsole uses "Feather Light X," the lightest midsole material in YONEX history, achieving approximately 30% weight reduction compared to general EVA materials and approximately 12% weight reduction compared to lightweight materials. In addition, by adopting a lightweight upper structure, the weight is approximately 220g per foot for a 23.5cm size, achieving a weight reduction of approximately 10g compared to conventional products. For the heel, "Endurance Rubber," which has been used for many years in tennis shoes, is used for the first time in running shoes. Also, the 3D Power Carbon built into the midsole raises the area around the heel, achieving high running stability, and its moderate flexibility reduces the burden on the muscles and generates forward propulsion. Furthermore, the Power Cushion in the instep area, which is the middle part of the insole and midsole, has been increased by 2mm in thickness, improving propulsion. In addition to high shock absorption, lightness and propulsion have been improved, supporting running that is less tiring even over long distances.
