I came across this product when I attended the OC marathon/half marathon convention. My right knee, left hip were still sore for 2 weeks after my long run and had flare-up of lower back tightness and spasms from previous back injury. This MuscleAidTape took care of my problem areas and helped me finish my first half-marathon, PAIN-FREE. I’m a big believer and will be stocking up in the future.
