Okay, first I have to admit I ordered the wrong shoes. Thought I'd order the mesh version, I got the leather version instead. This shoe is a MUCH better choice. The mesh comes loose quickly and can get a little dirty. Nevertheless, the grid is very practical. These shoes are made of leather. I have very wide feet. They fit perfectly and you can polish them (assuming you're not as lazy as I am) and that way they look good longer. I don't know how strong the sole is yet, but they are very comfortable. The memory foam looks as good or better than the previous version. I bought two pairs. Maybe I should have bought more. Shoe manufacturers change things over time. Will I be able to find this show in a few years? Does not matter. At the moment I have excellent shoes.
