I purchased these last year mid summer and my now 4 yr old wore them the rest of last summer and so far all of this summer although I need to order a larger size. I would recommend these as these are his go to sandals whenever he picks his own shoes out of his closet. Compared to Crocs these are half the price and well worth it.
I purchased Crocs online from the manufacturer and my 2 year old son loves them. I purchased a second pair from Target so he could have some variety. The sizes matched up the same as the one I purchased from the manufacturer. He wore the Target Crocs once for about 30 minutes and the strap rubbed his feet so bad that he now has two blisters on his feet. Very poor quality. I am going to try to return them, but not sure they will take them back. I do not want him wearing them again!
