Oofos recovery sandals. Purchased from a select shop and worn for about a month. There is some wear and tear, but there are no notable damages or stains, and they are in relatively good condition. Thank you. Size EU40 26cm Color Black OOFOS was founded in 2011 in Cohasset, Massachusetts, by a veteran team involved in product development for athletes, trainers, and major shoe manufacturers. They spent two and a half years developing the recovery shoe brand. While there are many shoes on the market that emphasize impact, they realized there were no shoes designed for impact absorption and recovery. They created OOFOS and became a pioneer in recovery footwear. The special material used in OOFOS products, "OOfoam," unlike the midsole of general EVA materials designed to generate forward momentum, can reduce impact by 37%, reducing the impact on the soles of the feet upon landing. This reduces the burden on the knees, hips, and back. The ergonomically designed footbed gently envelops the foot and firmly supports the arch. From OOFOS comes the classic item, the OOriginal. This simple beach sandal design is easy to use daily. The ergonomic design and footbed not only firmly support the arch but also successfully reduce stress on the tired feet, knees, and even the back. When you actually wear them, you'll feel your muscles naturally stretching, and you'll clearly feel the burden being reduced.
