Dave, I used the 5200. It takes 7 days to cure. I cut small patches out of a pair that was too far gone to save. I put a glob of 5200 on the tears and put a layer on the patch. Let it sit for 24 hours to tack up a bit. This stuff is SLLLOOOOWWWWW to cure. After 24 hours, i put the patches on, and it still wasn't tacky enough to hold. Pulled the patches off, and waited another day to put the patches back on. this time the patches stuck. I then went around the patch on the outside edge with the 5200 to taper the edge of the patch so it wouldn't catch, and peel off. I'll wear them at the end of the week to see how well it does. These rips are the uppers coming apart from the lower at the ankle. High stress area. If it works there, then it should work anywhere on the boot. Its a PIA, but beats paying another $140.00 for another pair if it works.

I looked at the Mucks today. They look to be built a little better as far as not having as many seams in the high stress areas. If these LaCross boots keep falling apart on me, I guess I'll try a couple pairs of the Mucks.
