OOFOS OOAHH UNISEX Black, Gray Recovery Sandals Size: 30 cm Purchased from an authorized online retailer. Used a few times indoors at home, but the size didn't fit, so I'm selling them. Please refrain from purchasing if you are concerned about minor details, and instead consider buying from a store. Introducing slide sandals from OOFOS that can be worn all year round. "OOFOS" A recovery shoe brand developed in Cohasset, Massachusetts in 2011 by a veteran team involved in product development for athletes, trainers, and major shoe manufacturers, over a period of two and a half years. They realized that while there were many shoes on the market that caused a great impact on the soles of the feet, there were no shoes designed for shock absorption and recovery. They created OOFOS and became a pioneer in recovery shoes. The special material OOfoam used in OOFOS products differs from the midsole of general EVA materials, which are designed to generate forward momentum. It reduces the impact of the rebound by 37%, thereby reducing the impact on the soles of the feet upon landing. As a result, it reduces the burden on the knees, hips, and back. In addition, the ergonomically designed footbed gently wraps the feet and firmly supports the arches. In the United States, understanding of recovery shoes has deepened year by year since its launch in 2011, and in 2017, it expanded to 1700 stores, mainly running shops.
