These used to run a size big. (a couple years ago) so, i bought a size small..well, seems NOW they run true to size. MOST COMFORTABLE flip-flop EVER!!I have always always loved them! fast shipping, good deal. I'm giving 4 stars because my only complaint is you Can NOT exchange through seller. You have to return item back to Amazon, then purchase something else, which takes longer.so i actually gave these to my mom and bought my size as well.
