I recently purchased a set of these insoles with the attitude that if they work cool if not they get added to the pile of failed tries. I own a landscaping company and I'm on my feet for hours, walk for miles and really put boots and insoles through the ringer. Anyways, I put the insoles in on a Monday and by Wednesday I could feel a serious improvement to my ankles, hips, and back. 100% improved. Look at your shoes, do you see the wear on the outside of the soles. Read Protalus recommendation they are on point. I'm at 2 weeks in work boots and I'm so satisfied and happy with this product.
