Bugabootoo's
I bought a pair of Bugabootoo's a few years ago as my first pair of winter peakbagging/hiking boots. They are very comfortable on shorter hikes, especially flat-land hikes. They're also comfortable in my snowshoes. They're very waterproof (even goretex can't compare) and are my favorite boots in the early spring when the trails start getting messy.
However; As far as a winter hiking boot, especially in temps below 0F and/or on rocky or icy terrain, they're terrible. First of all, like many of
Columbia's rubber bottomed boots as well as similar ones by
North Face and other companies, they only have 200 grams of insulation. This is fine for 20+ deg. days, but when you're on Mt. Adams at -10F and the winds are gusting to 40mph (a gentle breeze in winter
) you'll likely want a warmer pair of boots on your feet. Another problem is the lack of support (shank) in the bottom of the boot. This is one of the things that makes them so comfortable in the store, but on a rocky trail or worse, with crampons strapped on, they'll leave your feet all achey breaky by the end of the hike.
Plastic boots
If you're going to go climb some 14 k'ers out west or climb some vertical ice or maybe do a bunch of winter camping then by all means try the plastic boots. If however, your hiking is going be be mostly peakbagging and snowshoeing in New England then I think plastic's are totally unnecessary.
Leather boots
Between the rubber bottomed boots and the pastics are the leather boots. While not quite as waterproof as the rubber and plastic boots they're generally more suited to New England winter hiking that either of the others. There are hundreds of models of insulated leather boots avialable with up to 1000 grams of Thinsulate ultra. Many of them are available in waterproof leather and/or goretex or the generic equivalent. With leather boots you can also choose the level of rigidity you want. I've found that my leather boots are much more comfortable on the moderate or longer hikes, especially if there is rock-hopping or cramponing involved. The leather boots are also usually resoleable, I don't believe the rubber boots are. In addition, leather boots will protect your feet better than rubber boots and they won't be all covered with scratches when you return from a snowless hike atop the Presidentials.
FWIW: As others who've led group hikes in the winter can attest, one of the most common reasons people
bail on a winter hike is because they have inadequate footwear...on the group hikes I've been on, all too often rubber bottomed boots with only 200 grams of insulation are involved.....but, your mileage may vary.
For those considering new leather boots, you may want to consider the Rocky
Sport Utility Pro and the
Lynx.
Oh, and those comfort ratings like -20 and -65, don't pay much attention to those. They're useful for comparisons only. With only a 200 gram boot your feet would be ready to desert you after just 15 minutes or so of inactivity at -20F.
