I'm a retired RN who spent more than 50 years on her feet. After retirement, I developed plantar fasciitis in my right foot, leg pain, and knee pain to the point that I was unable to walk without a limp and a cane. My friend, an athletic trainer, said my problems could be caused by my right ankle, knee, and hip being out of alignment due to my flat arches and other problems. She told me about her success using Protalus insoles for her Plantar fasciitis and I ordered some the same day. After about 10 days of use, I'm no longer in pain and not using a cane. What a miracle!! Thank you!
