Derby house thermal boots are really warm, but only suitable for hacking riding wise as it can be difficult to get your leg on. But they are really warm for long frosty hacks
Hi, I wear Equitector boots and I ride in them, muck out in them - basically do everything in them and they are great. They have climate control so your feet are never too hot or too cold! They also have a stirrup balance system. Cant rate them highly enough.
I have the mountain horse classic rider, the waterproof ones they are amazing considering they are not marketed as a winter boot. My feet are normally freezing in anything. Not cheap but then worth it
also fabby for around the yard are the long muck boots toasty feet
