I got  size 3 for my son who wears 2.5.  They fit him great.  He has wide feet and high rise, and it's frequently hard for him to get his feet into a shoe, so I specifically wanted an adjustable shoe, and this one worked as I hoped.  They seemed comfotable, I heard no complains.   Quality-wise...  The shoes held up pretty well through a dozen trips to the beach, but today one of the insoles have come out and some of the icky, sticky glue ended up on the top of it.  I stuffed the insole back in, but that sticky stuff is pretty gross.  I will probably end up replacing them.  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.
