I was very skeptical about this product, but it is WONDERFUL!!!! I have been fighting ITBS for about 2 months. I am supposed to run in a 1/2 marathon next weekend but didn't think I would be able to do it because of my ITBS. I tried everything, but nothing seemed to help. I tried this as a last resort and I have not had one bit of pain since using it!!! THANK YOU SO MUCH FOR A GREAT PRODUCT!
