We are actually on our 5th pair of these (my daughter has had 4 sizes of pink, and my son is on his first pair of gray/green.  These sandals are a little expensive for kids' shoes, but they're very sturdy and have lasted until they're outgrown. They've done fine in the washer.  We use them in the hot summer months in place of sneakers, and they have good tread for running, climbing, puddle-stomping and playing. My kids have never had blistered or expressed discomfort. I'm sure we'll own more pairs!
