I purchased this shoes because of breathing mesh and gel soles. I need to wear at work tennis shoes and I got problems with fungus on my nails. Since I started to wear these shoes my problems went away. This are by far the most comfortable shoes with no foot pain I ever wore. After three weeks I caught my foot on cardboard box and the mesh ripped. After month they tore on several spots. After four months bottoms started to wear off and separated on both shoes. Very comfortable and very cheap made. But because they are unbelievably comfortable I'm buying the second pair. I whish they would put on the market more durable version of this incredible painless shoe.
