ASICS / KNEESUP Walking Shoes 24.5cm Color: Wine Size: 24.5cm Upper: Artificial Leather/Synthetic Fiber Sole: Rubber Accessories: Box ASICS focuses on the social issue that about one in four Japanese people have knee problems. The medical cushion control system is placed inside the sole, flexing when weight is applied to the heel and inclining inward, reducing the burden on the inside of the knee joint. ・Developed in collaboration with industry, academia, and medicine, these walking shoes are gentle on the knees and designed for people with a tendency towards O-legs, which is common in Japan. ・The MCCS structure (Patent No. 6868513) installed in the sole reduces the burden on the inside of the knee joint when weight is applied to the heel. ・The insole uses polyurethane material and a three-dimensional shape that wraps the arch of the foot and the heel, enhancing the fit. ・The outsole incorporates a thick sole design for shock absorption and a boat-shaped design for propulsion. ・The shape of the counter (heel counter) has been refined to enhance heel hold. A special design with different lengths inside and outside is adopted. ・Reflective materials are used to improve nighttime visibility. ・Seamless materials that pursue lightness are used for the upper material. My husband bought these for me, but they are a little too big, so I am selling them. Only tried on. No smokers. No pets. Thank you. Thank you for looking.
