So sad about this. I purchased these shoes a month ago, and they are already worn and have thinning areas. I saw that on other reviews and ignored it. How bad could it be right? These people must be working their shoes to death. Wrong wrong wrong. I previously purchased the Vapor Glove 2, and loved them. Wore them to the ground. These I've been wearing for a month, and only when I work. I am a nurse but it's not like I'm running marathons daily, and I use them indoor only. I would return them, very gladly, but my return window ended yesterday.
