I've been an athlete my whole life and have tried countless cleats to treat flat feet. These are by far the most comfortable boots I have ever bought and have reduced the pain caused by my extremely flat foot. I bought their wide version half a size up and it fits just right. I love that the sides are soft and flexible and the shoe never felt like it would fall off while sprinting. Flat feet are always going to hurt no matter what, but this shoe has done everything it can to reduce that aches and pains during activity. So very happy with this purchase.
