The crocs website suggests you order a size down if you're a half size, so I ordered these in 7B(M) (I'm usually about a size 7.5 US/5.5 UK/38 Europe & India) and they're perfect. The pink color is not as bright as the picture shown, it's duller, but comes across as a nice subtle shade. The sandal is unbelievable light - feels like I'm wearing foam.
Two things I would warn about though - (1) the movable strap sits snug (my friend who's the same size as me finds the strap tight so she's ordering a size 8) and (2) the part that holds the button on the inner side of the foot, touches my foot (so there could possibly be rubbing - I havn't worn and walked in the sandal long enough to find out).
Wonderful sandal from crocs! :)
