I got size 10 for my daughter who wears size 10.  Fit-wise they are ok once the foot is in, but I could barely stuff my daughter's feet into her shoes, and she has medium width feet.  So I would suggest going one size up on these.<br /><br />Quality-wise...  One of the shoes started to unravel in the back, where the opening for the draw cord is, within a couple of uses.  Also, the stiching around the insole came apart slightly, which wouldn't be a problem on its own, except a few small pebbles got between the rubber part and the fabric on the top, which were almost impossible to get out.  I finally replaced them with something else, we probably got 6 or 8 beach outings out of them.<br /><br />So the bottom line is: if you need something for a one- or two-week vacation, these shoes will do just fine (whatever you get, it would probably be a throwaway anyway, since kids' feet grow so fast).  If you need something for a whole season - spend a bit more money, and you won't end up looking for replacements before season's end.
