these are probably at least 1/2 size larger and they are much looser fitting. it play the noise. Only reason I saw it was because I looked down as I was getting back in my car. its that good of a product. We shall see if it works as good as those. ) I just had to write this review after seeing shoes that were very worn and complaints. (Written by my gf) So colorful Enjoy the product. They are very comfortable and true to size.
