I put about a foot on each pole during my thru and when I figured I'd try finally try to temp fix a shoe, it was so stuck to itself after being in the elements for so long that I couldn't get even 1/2 inch off without creating a sticky mess. So now I just leave it home. That was the only time I ever tried (or needed) any. I managed to get to the next town and fixed it with shoe goo and that lasted until I found an outfitter in the next town. So I probably won't be bringing any the next few sections and on my next thru.
