I have fallen arches, plantar fasciitis, arthritis in my knees - if you can imagine a pain with legs, I have it. I have worn prescription orthotics, tried every insert. I was at my wit's end and I saw your ad on Facebook. I read all the reviews and thought I would try it. My order came in the mail today...I was about in tears from the aches and pains. I put the Protalus in my shoes and instant relief. I wish you made houseshoes or footies/socks with the insert so I could wear them to bed!
