I've bought at least a dozen pairs of insoles over the years, including 3 custom made ones from a podiatrist and chiropractors. My feet hurt so much all of the time. Protalus insoles are the best ones I've ever tried. I just bought my second pair so I can keep one pair in my workout shoes and one in my work shoes. I'm on my feet a lot at work which is all concrete and I have no more pain. I'm so happy that I tried Protalus!
