I have hard plastic arch supports that help my feet and lower back, but because they're hard, I can't run in them, and by the end of the day, the bottoms of my feet often hurt because of the firmness. Before these specific Dr. Scholl's supports, I've NEVER found soft ones that worked for me AT ALL. I bought a new pair of running shoes right before Memorial Day, and while in Colorado 2 days later, we decided to climb "The Incline". So I went looking for soft supports AGAIN, and found these, hoping they'd work (and keeping the receipt just in case they didn't). ALL the way up that mountain, and then ALL the way back down over rocks and uneven winding trails, and at the end of the day (and since then), NO PAIN WHATSOEVER! ZERO! True story. They even work better than ones I had professionally made.
