I am a runner and a hockey player. My feet are flat as a pancake. As a result, I suffer from knee and lower back pain that causes fatigue and lowers motivation to get out and do things. I have tried SuperFeet and other footbeds, and they provide some arch support but ultimately lead to greater pain in the arch. About a year ago I was given a pair of Arch Mobility inserts that, in effect, integrate an orthotic into a footbed or insole. I was skeptical at first, but I slipped them into my shoes and could instantly feel the effect of better alignment. I’ve been surprised at how well these work. It’s been nine months I can’t imagine going anywhere without wearing them. They are well worth the $40. In fact, I have purchased five pairs. You will feel the difference immediately.
