Just wanted to let you know how happy I am with my EZ Run Belt. I received your shipment on Saturday (thanks so much for the speedy turnaround on my order), and I used it for the first time this morning. What an amazing effect it had on my technique. I’ve been struggling to stop heel striking for months, and with your product I was immediately and continuously up on the balls of my feet. I kept the belt on through the full four miles of my run, and while I can tell my calves are going to be screaming at me for the next couple of days, the foot pain that has been plaguing me was not there at all. Many thanks for the brilliant system you have designed. You have made running enjoyable for me again!
