These shoes have a very softly cushioned insole with a slippery fabric covering. The material feels luxurious at first touch, but because the soles of your feet slip on the insole when you walk, the strap digs into the top of your foot. You have to flex your foot just to keep the sandals on. I have abrasions on the tops of my feet created when I walked for about 3/4 mile in these sandals. Now I wear them only with socks, and never to walk very far.
