I have never had such an uncomfortable pair of sandals ever. I thought that they would get more comfortable with time but was I wrong! At first it was rubbing at the base of my big toe on each foot, which I dealt with with bandaids. After awhile it developed into a nagging pain. It was as if the whole weight of both feet were being carried by my toes.
I can only assume that there is something wrong with my fit with these shoes or something is wrong with the design. They are so much better looking that my other similar workout sandals so I am really disappointed.
Too late and too expensive to send them back at this point.
