OOFOS sandals, size 39, 24.5 cm! Used only about 5 times. The soles show no wear and tear, so they are in beautiful condition! "OOFOS" was born as a pioneer of recovery shoes. The special material Oofoam used in the products differs from the midsole of general EVA materials, which are designed to generate forward momentum. It can reduce the impact of the rebound by 37%, reducing the impact on the soles of the feet upon landing. Therefore, it can reduce the burden on the knees, lower back, and back, and the footbed designed based on ergonomics gently wraps the feet and firmly supports the arches.
