They helped me and my poor heel — to my surprise.
At 59, I had painful bone spurs of the first time — in my left heel. I really didn't know why I felt pain like this off and on. It was hobbling me at work. A wonderful podiatrist x-rayed the foot, gave me Powerstep insoles and a set of easy-to-follow exercises. The best exercise was designed to stretch the calf muscles. (See? The leg bone IS connected to the heel-bone.) In any case, the pain disappeared within days, as I recall, and I was active again, even resuming my walking exercises. The insoles are firm and fit nicely in my main shoes and running shoes, but in some shoes I own there wasn't room for the insole AND the foot, and it's not practical to remove the shoe's original insole. In other words, you need enough room between the sole and upper; that's the only thing to watch out for. Buying a larger size shoe won't be the solution. In any case, my feet have felt so much better that I can wear shoes without the insoles on occasion without the pain returning. (But I'd prefer to wear them).
