I don't know them. But for that price you can find boots with tons of reviews. That's a decent budget for some insulated boots.
yup, I should have mentioned that I have a pro deal with Merrell at 40% off, so I'd be looking at paying $120. I dont know how closely your read the specs either, but that coldsmart technology looked nice. I dont know of any other boots that have it. My thought is...they would be really warm while I was sitting, and quite a bit cooler for when I hike around.
