I have a lot of trouble with my right foot. Surgery only made it worse. I saw the ad for the Protalus insoles on FaceBook about a year ago. I only bought one pair. Today I was thinking I need to replace some insoles in other shoes and this ad popped up. But let me back up. I am seeing a new foot specialist. He took my insole out of my shoe and showed me how good it really is for my foot and its problems! He was delighted that this was my choice. Now - today - I have purchased two more pairs and will only put these in my shoes going forward. I cannot wear heels and "pretty" shoes, but who cares. My feet feel better and so do I!
