Well, I re-read that earlier thread and it's all starting to sound familiar.
I think if I had a bad experience with GoreTex, I'd be gun shy too, but I've had 3 pairs of Meindls and have not yet had a leak. The 1st pair were retired at 14 years because the seam stitching was just totally worn out. I could still stand in the water with dry feet, though.
I think any boot can be made waterproof. My problem is that it usually makes them air-tight too. My feet sweat like a couple of race horses and if my boots aren't breathing, my feet get cold.
Until I get burned, I'll stick with my good-fitting leather boots with GoreTex lining thanks.
