I am a 67 years young and have been running five days a week for 30 years. I started having pain in my sacroiliac joint on my left side. I went to physical therapy to strengthen my Core. It helped but I was still having pain. I saw your advertisement on facebook. I have always had a problem with my left foot falling inward. I started to think that if that foot was corrected it might solve my problem. I ordered a pair of your soles and the VERY NEXT DAY I could feel the difference. I have been wearing them two days and I have NO MORE PAIN. thank you.
