The most comfortable boots I've ever had. And they look cool! Warm down to 15° and likely colder temps, though I've not yet had them in colder conditions. Wide tread is sturdy, grips well, good on ice. The boots are too low for deep snow, especially compared to my ancient LLBean 10", felt-lined (nowadays GoreTex/Thinsulate) boots (currently $164.) Zipper fastening is efficient, but definitely needs a larger, looped toggle (or I need much stronger fingers) for easier pulling closed. And needs a longer tongue, up over the top of the boot, for better padding: when zipped tight, the top pushes uncomfortably onto/into my lower leg, so I generally only zip them up about two-thirds. A good boot that could be better.
