I was a little concerned initially purchasing these because I have the original air mesh ankle boots. I bought these for the fit, and some reviews said it is nothing like the original. I was pleasantly surprised to find that they fit quite well, and the size is equal to that of the original boot. The waterproofing works, and they came with an alternate set of laces. The only cons are that the back is a little too stiff (which I'm sure will loosen over time) and the padding inside isn't quite as firm as the original boot. Overall, I am quite pleased and found it to be a great purchase.
