First ordered this pair in an 8 - too small, sent back ordered a 9 -- too large, sent back, decided to try another 8... and this 8 fit but is slightly loose. Oh well - I'm keeping them because they're kinda cute and I have a terrible time finding shoes that fit. On the pro side, they do have good arch support (which is hard to find these days) and the soles are comfortable. On the negative, this is the 2nd pair of Crocs I've had that rub a blister on my toe. But I have bandaids, so I'm keeping these as soft, arch-supportive shoes are what I need for our hardwood floors.
