Actually this was my second pair already. I bought one pair last summer and our LO loves it, so I bought another pair this summer. I was even recommending it to my friend until one day (2 months after using) I found the heels of the shoes have been worn down completely. I looked at the pair we used last summer and yes, same issue. They were worn down so badly that the label at the back of the heel was completely gone! I have never seen things like that before...So, sadly I threw both pairs away.
