Purchased a pair of size 9 and they are a bit tight. (with any socks they are too tight.) Ordered a pair of 10s ( as they do not even offer half sizes) . the 10s were much too big and looked like clown shoes in comparison. I could not wear these at all. When I returned these, I had to pay shipping, ok, PLUS my refund was issued today sans a 20% restocking fee?!  Soooo no half sizes for a better fit, they are a shoe Co. after all... and 20% restocking fee...
Fortunately Amazon refunded both costs to me but its no more crocs for me -Ever.
