OOFOS OOriginal Black M10 W12 EU43 (29.0cm) Purchased from Murasaki Sports. Please check the condition in the images. If you have any questions, please feel free to ask. OOFOS is a recovery footwear brand that was born in Massachusetts, USA in 2011. A veteran development team consisting of experienced shoemakers, top athletes, and trainers worked together for about 2.5 years to create a completely new recovery sandal. From the problem that conventional shoes generally have strong impacts from the ground and body weight, and also put a lot of stress on the knees and lower back, they experimented and succeeded in commercializing a product that can absorb the impact and reduce the shock when landing. The special material "OOfoam" used in OOFOS is different from the soles of general EVA materials, and is a new material that makes it possible to suppress the rebound of impact by 37%, and its shock absorption reduces the burden on the knees, lower back, and back. As the name "recovery" suggests, it refers to sandals that aim to "recover fatigue" in the legs. It features functionality that reduces the burden on the legs and lower back caused by walking by adopting a footbed (insole) that fits the soles of the feet and a sole with excellent cushioning. It has become popular in Japan among runners and people who enjoy sports for several years. It is popular as an item that promotes recovery from fatigue caused by daily workouts. Anyway, when you wear it, the concept of sandals you have worn so far will be overturned. You will feel like you are walking on clouds. Once you wear these, you can't go back to hard sandals.
