I have loads of crocs and already have a pair of these but wanted another pair to leave at my son's house. I orded a UK 6/7 what came was a 7/9 far too big. So I ended up having to pay the postage to return them
I got the size 4/5 adult at a great price and delivered the next day too....I have been wearing them since yesterday and they are very comfortable and everything you would expect from Crocs. I am very happy with my purchase and would highly recommend them to anyone. They are a unisex design.
