The shoe soles feel great, but the main straps are made of a rough webbing material.  I know it would cause blisters on my skin.  I love the style and they could have been great.  The straps feel like a stiff nylon packing strap.  My other Keens have a nice soft material next to my skin. I guess some people have really thick tough skin.  I don't know what the designers were thinking.
