Just wanted to tell you how much we love the Chi product!! You really should contact RUNNER’S WORLD magazine and get some advertising in. My 14 yr old daughter rolled her ankle 2 days prior to our County Championship Track Meet (10 schools) We “child” her for 2 nights and she not only won, but got a PR. We had to Chi her leg prior to the Jr Olympic State Championships which had a knot in it, she went on to WIN the gold medal and State title for the 1500m. We really believe in CHI and tell everyone we meet in the running world! Thanks for providing such a great product!
