I have never been so impressed with a product – any product, for that matter! It’s revolutionary, and it works – take it from someone who has truly suffered over the course of 15 months – trying everything (to remedy a sore Achilles tendon) with little success, until Arch Mobility came into my shoes. Remarkable and after a mere five days, my Achilles (both, even though my left was always sore during and after exercise) are pain-free, and for the first time in over a year, I had an intense 1 ½ hour bike ride completely pain-free. WOW!!
