I bought this sandals to my son when he was 2 years old. I got them one size bigger and worked like a charm. It was rommie enough and it adjusted just right thanks to the velcro straps at the top and at the back. He loved them. The sandals are very durable, it doesnt slip, washes very well and it dries really fast. Great for summer. It still looks fairly new and now it is going to my youngest son's feet! Getting a new pair for the big brother.
