Sizing/style is not consistent. I first purchased the navy and pink flip flops in a size 7, which normally would have my feet filling almost all of the footbed. Oddly, these fit more like an 8. But they were very comfortable so I kept them. Then I ordered a pair in black, also size 7. These actually fit like a 7 and are shorter and narrower than my other pair. The entire footbed isn't as thick though. Not sure what the deal is with Vionics manufacturing? These are supposed to be the same flip flop, but they seem like they are different styles.
