I’ve always loved MH boots. I know Ariats are quite popular and I feel like everyone and their mother always recommends them to me, but they’ve never fit my foot very well and is why I ended up with MH in the first place.
I finally replaced my old MH tall boots (bought ~10 years ago) with a new pair. I was worried in the 10 years I’ve had them, the quality might have gone downhill, but I’m pretty pleased with them so far and they seem to be good quality. I’d expect similar quality in their paddock boots as well. At your price point, you could probably even buy a pair of normal ones for summer and one of their winter styles if you found them on sale.
