Rated 4 out of 5 by from Good boot, but... I bought a pair (11.5) for myself and a pair for my wife (6). I can get mine on/off no problem but my wife has very high arches and simply can't make the boot work. Too bad, because they are comfortable and warm, warmer than my Snowburbans,,,,,but, the lower lace has twice pulled away from the little closure stub....that shouldn't happen even once, and I'll now need to glue it into place. Fix that, and a you'll have a great boot.

Rated 5 out of 5 by from Dual lacing system. My right foot is one inch wider then my left due to an old surgery. Being able to keep the bottom part of the boot loose while the top fits perfect was just what i needed!!!!

Rated 2 out of 5 by from Not enough support I love the look of this boot and how high it comes up my calf. But that is where the positives end. First, they're difficult to get on. They have no support in the ankle and an excess of material on the top of the foot. The pull strap on the top of the foot is quick and easy, but then there is no place to strap the excess and it just hangs on the ground. Plus overtime, as you walk and move, it loosens. The mechanism isn't very strong and you have to readjust the strings every 10 minutes or so.

Rated 2 out of 5 by from Great idea, but not quite implemented correctly. I picked these up to replace my old Vasque Arrowhead Ultradry boots. I read reviews and purchased a size up from what I wear in my Vasque Sundowners and Ultradrys. Still they are too tight. But more importantly they are impossible to take off. I might have I torn a tendon in my ankle taking these off. I wonder if the folks at Vasque even tried these out before producing them?

Rated 5 out of 5 by from Winter slipper on steroids! Took these out snowshoeing in Northern UT & they were great! Very comfortable, always warm/dry and didn't ever feel overheated. They worked well with the snowshoes, no pressure points from the bindings/straps etc...really appreciated how lightweight the boots are. If you want a little easier time putting them on, I'd suggest removing the liner, put your feet in the liner and then put on the shell using the pull tabs. Many winter boots can be clunky/stiff and these were definitely not, they performed great trekking and around town. I really like the style too. Grip was good, but was expecting better performance there.

Rated 4 out of 5 by from It works, it fits. If you use both the supplied pull hooks, they go on easy. I've got a size 12, and it's not a problem.

Rated 5 out of 5 by from Perfect For Brutal Utah Winters! I do intensive off-trail hiking every Sunday in Utah. I bought these a month in advance, before any snow had fallen, after seeing them in the catalog, just so I'd be ready for the first large snow-fall. I took these up Snow-Bird Canyon, after about two feet of fresh snowfall. They performed stunningly! My feet were never cold, not even after trudging through an ice-cold river of snow runoff, multiple times. I let my brother borrow my gaiters since his shoes were only 6-inch, so I did get a little snow inside but it never bothered me one bit since wool retains its warmth, even when wet. I was worried that the shoes may not be waterproof since on the website and catalog it only says "Insulated" in the specs, but the description says "Ultradry Membrane?" Needless to say, they are lightweight, warm, and waterproof. Can't wait to take them out again! P.S. They are a more light-weight construction, which you will be thankful for after trudging through the snow for hours; but I would recommend using only in the snow, for fear of wearing out quicker in less specific environments. Hope this review helps!

Rated 1 out of 5 by from No temperature rating for a wnter boot, ridiculous! Bought these online, great new version of a mukluk, great fit, sturdy but all of this is completely useless as the boots do not coe with a temperature rating. Why sell winter boots without one? Ridiculous.
