So working in a busy ER I needed a pair of lightweight shoes that are fluid proof. Ive had Crocs before and really liked them. I bought the size I normally buy and these are kinda big.... I don't think a size smaller would make a difference because I also have a wide foot. The biggest issue is they STINK!!! I understand its a plastic shoe but my feet get so hot and sweaty its unbearable and I cant take my shoes off because the smell would kill my coworkers!!!! I hate to try powder to make an already roomy shoe which will make my foot slide even more.
