My niece loved these.  They seemed to run a little big on her, but due to the timing of her birthday it worked out since she had room to grow before the following summer.  Crocs are a great product and in my opinion much better/safer for little kids to wear than flip flops for the beach, etc.  You can't kill these things, and they were still in near perfect condition by the time she outgrew them.  This particular set of crocs had more of a "contoured" look than some of the other ones I'd purchased.  She loved them, but I am not sure the same style would have been as appropriate for a boy.
