Saved my life at the SPARTAN BEAST (13 miles, 30 sets of obstacles, 97 degree heat)
Last weekend: 13 miles, 30 sets of obstacles -- including mud pits that filled my shoes with sand and pebbles -- and 97 degree temperatures.<br /><br />I can't imagine how miserable I'd have been without this product.  I've tried to run through a blister before and it's awful.  But this weekend, I was fine.  No chafing at all.  This is a remarkable product.  I don't use it for everyday use at the gym on the treadmill, but whenever I'm going on a long run, this is a must have.
