I really wanted to love these as I like how they look and they felt comfortable on my foot. However I wore them in my house for about 10 minutes took them off and put them away. The next morning I had big red swollen areas on my ankles where the straps were. I have boney ankles and the strap sits right above my bone (where with my tevas and other sandals it sits at or under the bone). I know everyone says they will break in but I don't want to take a chance and I am sending them back. Its too bad because I wanted a pair of Birkenstocks with ankle straps and loved this style
