Footbed is very comfortable BUT the straps are not. The part where the straps criss cross is where it doesnt lay flat on top of your foot and therefore rubs against it.  At the end of the day although the bottoms of my feet feel great, the top of my foot have marks and I feel the straps where they intersect at every uncomfortable step. :(

I have a thin to average thickness of a foot, where I typically do not run into this problem with sandals so this tells me they obviously don't test their shoes with people actually wearing their designs
