My feet hurt with every step that I take. I am a professional and I want to wear pretty shoes with a small heel but I rarely do because of the pain. I decided to try Protalus and today is day 1 in my 2.5 inch heels. My feet do not hurt. I spent more time on my feet to test them and I am shocked. I bought a pair for heels and a pair for my workout shoes. I hope this continues. If so, I will definitely buy more to have on hand.
