These sandals are so cute. I always order 1/2 a size up in sandals and was very surprised and very disappointed that I can't even get my feet into these. I wear Steve Madden shoes all of the time. I now have a very cute pair of sandals that I can't wear. The shipping cost to return them, is keeping me from returning them so I'm stuck with them. It's a shame. Very disapointed....
