I positively live in zip-up paddock boots, the cheapest, cheesiest brands out there, and I've never had a zipper break. Usually the sole falls off before the zipper gives a hiccup, lol. I just got a pair of Dublin field boots with the zipper this spring, and they are also holding up well (broke in but being babied due to my inability to buy new good tall boots anytime soon, ha ha). Maybe when my ship comes in I can get a set of Ariats (A gal can deam, can't she??
). Sorry yours didn't hold up, kitten_Val, I hope you can exchange them.
