I have the tall Arctic Muck Boots. Nice and warm, and waterproof, and the mud doesn’t suck them off. I also bought a pair of just above the ankle ones, which I ended up giving away because they rubbed my leg.
I also have a pair of the Muck Boot Pacy II tall boots. These ones are cut narrower in the foot so they can be ridden. They even have a stirrup rest.
If you watch Zulily there are good deals to be had when they are featured.
