I purchased this Crocs for my two year old. At first they were great, could not be more happier. He loves them. However after a week the button that hold the strap to the shoe started to break the skin on my baby feet. So now, he can only wear them with socks, which defeats the purpose of using this kind of shoe. The company needs to review the design and provide some kind of protection to avoid the friction. Otherwise they can cause injuries.
