I hated crocs (generally), but frankly they are a great shoe when on the run & your kid cannot tie his own shoes. Love these particularly because they can be worn in the fall/winter/spring when it is too cold to go with out socks (in regular crocs). My son outgrew his 10-11, thus got size 12-13 in these and they happen to stay on better than the non-lined version (since he feet are a bit on the small side to wear the size). They seem to be decent at resisting dirt too.
