I have been running distance for 10 years, but the past 3 years have been with the newest member of our family, our 85 lb. dog, Buddy, who loves to run distance.  About 2 yr. ago I developed a problem with my foot, causing extreme pain in my toe, then numbness.  Needless to say I just about gave distance running.  I tried many different things, including a cortisone injection in my toe, but with no luck.  Then a friend sent me a link to your website.  The first day I ran hands free with Buddy, was incredible and fun and easy.  We both had a tremendous run.   I have been using the hands free device for the past few months and my foot is making a turn for the better.  I am not constantly having to "reign" Buddy in, we are both "free" to run and enjoy the sights, smells and joy of distance running once again.  Thank you  Cardio Canine!  You were a lifesaver for me and Buddy.
