Mine are from a local tack shop, they were my mom's 20 years ago, and they've held up amazing--they still look new. No zippers, which I like because I don't like the look of zippers, and the brand is "International Boot Co.", but they might have been made by the tack shop, I don't really know. Wish I knew where they were made so I could get another pair! I also like the second pair MIE posted
I'm not allowed to get zipp up boots. I have the Devon-Aire Ladies Nouvell Pull On Boots. I have to say I love them, once you get past the break-in stage they are really comfy. I've had them and ridden in them 3xs a week for 3 years and they're holding up strong. If you have a good boot jack and it fits you around the calf right (or have pull on hooks) getting them on and off is apiece cake. And if you do get pull ons and buy a book jack, beware of local tack sttore ones(all the tack stores I've been to have stapled ones, maybe not yours)... if you can see staples don't buy it! I bought mine and and after a few times using it the staples bent and the frame came undone from the stand, my dad had to remove the staples and screw it together.
I have a pair of Devon-Aires now, they are about 10 years old, they look brand new. They are so broken in that I don't need any boot jacks or hooks to get them on or off. They are really nice boots, but they slide down, and twist when I ride. Also they are a tad too short for me. I didn't know they still made Devon-Aire boots without zippers. I couldn't find them anywhere. I will look harder, and probably get a pair of them again. They are really comfy.
I have a pair of Ariat pull ons right now but I am waiting on my custom boots to come in and I did get those with a zipper. I have trouble fitting boots to my ankle as I have a big foot, big calf, and small ankle. With the zipper I can get a boot that is small enought to fit my ankle so it doesn't make my leg look like a tree log.
Haha, I bought Ariat Heritages with zippers, and about two years later the zippers popped off both. Luckily, Ariat replaced them for me for no cost, and the zippers are much more heavy duty now. Not as attractive with the big chunky zippers, but they were free, so who am I to complain??
Apart from the difficulties getting them on and off, I see why you want them, they are much more attractive. I would try Ariat again, just because I had such luck with their customer service (even though the zippers broke, which they told me was a common problem with my style, which is why it was since retired)
