Retail Price: ¥14,080 Size: M6/W8 (25cm) I bought these to wear during a hospital stay, but ended up wearing something else, so I've only tried them on indoors. This type of OOFOS shoe is hard to find, and I had trouble looking for them. I think they're perfect for everyday wear, as well as for work. For those who aren't used to recovery sandals. Model "OOcandOO" allows for adjustable hold. These recovery shoes allow you to adjust the fit with the Velcro straps on the instep. They reduce stress on the ankles by 47%, and are also useful in medical settings. OOFOS's special sole, "OOfoam," unlike the structure of performance shoes made of general EVA material, which aims to generate forward momentum, suppresses impact rebound and reduces the impact on the soles of the feet upon landing, thereby reducing the burden on the soles of the feet, as well as the knees, hips, and back. In addition, the footbed, designed based on ergonomics, gently wraps the feet and firmly supports the arches.
