My daughter had blisters around her ankles after wearing these, which I expect with any new shoes, especially sandals. I just put band aids on the blisters and had her keep wearing them. After the blisters healed, I'd thought they'd be fine but she got blisters again in the same spots. I again put band aids on them until they healed but the blisters came back for the third time (she had been wearing them nearly every day for awhile now by this point). I'd give this a lower rating except my daughter didn't really complain about the blisters and once the blisters stopped coming back, they were great. We both loved how easily these can be put on and taken off (a big plus when we are running late!). These are her favorite shoes to wear, and even though she has outgrown the pair she has, she keeps wanting to wear them so I just ordered a bigger pair. Blisters, here we come.
