I recently began googling for DIY ways to fix my slick soled 1+ year old Keens (out of warranty), which have become very worn down. After reading up on possible retread methods like gluing actual tread from automobile tires, I decided to see if there was a simpler way to go about giving my Keens their edge once again. I wanted more than the sandpaper or a glue method since I would find myself on river rocks soon and didn't want to find myself cussing out the 100 grit paper. or shoe goo. With Dremel in hand, I laid claim my Keen's tread once again and would like to share with you my pursuit of the perfect retread.
Sweet moves ! I just googled for a "tire groover" and see what you are talking about. Could come in handy for any rubber meets the road device. Many thanks for your comment Shawn.
