I have the shoes for my son (16 months) ordered to use it on the beach and in the pool. The shoe is relatively slightly and allow to tighten well. My son can also run well in the shoes. But the seams on the back drawstring have broken after a few weeks. For the low price I can live with it - the shoe is supposed to just hold a summer - but more than one child will not survive the shoes up. For small children with rapidly growing feet so ok. Next year, when my son is still on his feet, but I will probably then still buy the high end shoes from other manufacturers.
