The zipper in one of my favorite boots broke and one of the zipper teeth actually fell out, so there was no hope. I took the boot here and the zipper was replaced perfectly and quickly. It cost $30 for the replacement, which was reasonable to me because I LOVE these boots. I would definitely recommend coming here for any shoe repairs.
And...last night the zipper in the other boot broke, so I'll be returning to get that one replaced. In all, my zipper repairs will have cost around as much as the boots themselves cost, but when you find perfect boots, you stick with them!
