I live in North Dakota and I have tried the rated columbia, they keep your feet warm, but, they are impossible to ride in, they don't flex and are usually too big for stirrups, I have been reading alot on the Mountain Horse boots, has any one had any experience with them?
I have a pair of Mountain Horse Rimfrost Rider winter boots for sale that I outgrew. They're in great shape and kept me warm in low temps. I highly recommend them. If you're interested, I posted a thread with pictures here not too long ago. Size 8. Posted via Mobile Device
I have these. So far they are very toasty warm at 20 degrees but they are rated to -40. Very comfy to ride in, fit in all my stirrups and I don't have any oversized ones. English and western. And I've tested their waterproofness, it's perfect all the way to the top lol.
