I have had my Cloudsurfer shoes for almost a year now and I am in LOVE. I have had a huge struggle with shin splints and stress fractures since running cross country years ago. No matter what inserts or shoes I tried, they always redeveloped and left me in pain. I was told I could no longer run consistently. A friend suggested that I try On and further suggested the Cloudsurfer due to my injuries. He does Valet at a popular hotel so he is running miles and miles a night and swears by these shoes, so I decided to give them a try. You actually feel the difference instantly when you are running, it is amazing. Even better, I have been able to run when I want, as far as I want, without ANY injuries or pain. Thank you for such awesome shoes! If anyone is on the fence, try them, you will not be disappointed!
