....Does what it says. I used Freesole to repair some expensive Merril Winter hiker sole delams, and put a toe guard and repair a rand on my Lowa leather hikers. All with one tube. I've beaten both boots hard and so far so good. I'm impressed that sharp granite hasn't nicked it - yet. Go to McNett's web site for tips, and Backpacker.com. Its only as good as the prep you put into it.
