NYC Marathon 2016
I bought my first pair of Cloudflyers at the NYC Marathon expo and then did the runners cardinal sin. I ran the NYC Marathon the next day in my brand new pair of shoes. And let me tell you, it was the best decision I made. They were amazing and comfortable to run in. In addition, I didn't have any blisters after the race. Now I don't recommend buying a brand new pair of shoes and run a marathon in them. But if you do, you might look at On shoes.
