Reading the reviews I thought these would be perfect for my 1 1/2 year old grandson. They were cute and seemed to fit well. But, he had them on for about an hour and he kept wanting to take them off. I took them off and the insole of his left foot, where the strap had been, had been cut pretty badly (a little less than 1/4 of an inch). The insole of his right foot was also cut but not as badly as his left.  It has taken about a week and a half to finally start looking better.  He doesn't have problems with other shoes, so maybe we just got a bad pair. If you decide to order these I suggest feeling inside at the straps to see if there are any rough or jagged areas before putting them on.
