This shoe has a big problem. The inside of the shoe is very slippery. As you walk, your foot constantly rubs against this surface. The leg does not stand still, after a while the skin becomes covered with a rash and begins to hurt. No matter how tight your shoes are, you won't be able to solve this chafing problem. The inside of the shoe should stick to your socks and be sticky (or at least not slippery) to keep your foot in one place while walking or running. You may think that a professional shoemaker is worth that much now, but you are wrong. Avoid this product if you are going to wear it.
