The best winter boots for men
The Insider Picks team writes about stuff we think you'll like. Business Insider has affiliate partnerships, so we get a share of the revenue from your purchase.
The Insider Pick:
With a great pair of winter boots on your feet, snow, ice, and the frigid temperatures won't stop you from having fun or getting your work done. We considered insulation, tread pattern, lacing systems, and more to find the best winter boots. The Columbia Bugaboot Plus III Omni Cold-Weather Boots are our top pick, thanks to the comfort, support, and amazing insulation properties of these boots.
My favorite boots are comfortable, supportive, and have great treads for hiking on all sorts of terrain. They're reliable, they look great ... and they tend to spend many months of the year tucked away on a shelf instead of on my feet. Why? Because they're just not winter boots.
Boots have to provide two qualities to be suitable for use during the winter: insulation and water-resistance. If your boots can't help keep your feet warm and they can't keep your feet dry, then they're just not suitable for wintertime use. And of those two imperative qualities, waterproofing is the most important factor.
Once your socks grow sodden after snow, slush, or rain inundate your footwear, the insulation properties of the boots are no longer of much importance. In the winter, a wet foot is going to be a cold foot, and one more prone to blisters and infection. So while you can always help keep your feet warm with a pair of socks (or with layered socks), you have to use waterproof boots if you'll be hiking, working, or just walking around in areas liable to see snowfall or rain during those colder months. It's no coincidence that most of the boots on our list have the word "waterproof" right in the product title.
But what makes a great winter boot, beyond the warmth and dryness? It's largely relative. You need a winter boot that offers sufficient traction for activities in which you partake, but you don't need the same level of aggressive tread pattern for slushy sidewalks as you do for snowbound trails. You want enough support to help prevent a rolled ankle if you slip on ice, but your winter work boots probably don't need a calf-high rise. You want a lacing system that's snug and secure, but you also want it to be as simple as possible, as you might be wearing gloves or dealing with frosty fingers.
In short, you need to choose a boot that fits the places in which you'll use it and the tasks at hand in said locations. Don't choose a winter boot because it has lots of nifty features that seem clever and keen; choose a winter boot that's going to serve your purposes. We've rounded up the best winter boots you can buy for different use cases and styles. Read on to see which of our picks is for you.
Although the Columbia Bugaboot Plus III Omni Cold-Weather Boot is our top pick, for the reasons laid out in the slides below you should also consider the Ever Boots Ultra Dry Insulated Waterproof Work Boot, the Wolverine Vortex BOA Winter Boot, the Kingshow 1017 Waterproof Winter Snow Boot, and the Timberland White Ledge Waterproof Boot.
 The best winter boots overall
Columbia/Business Insider
Why you'll love them: With the Columbia Bugaboot Plus III Omni Cold-Weather Boots on your feet, you are going to be toasty warm even when the weather isn't, thanks to the advanced insulation and lightweight design.
The Columbia Bugaboot Plus III Omni Cold-Weather Boots will keep your feet dry if you stand in a stream or puddle. Seriously, you could just step right into the water, and provided it didn't crest the impressive seven-inch rise of the shaft, your feet would not get wet. And were the stream or puddle into which you stepped freezing cold, your feet would stay nice and warm, too. That's because these exceptionally well-made winter boots come with a 200-gram insulation and an Omni-Heat reflective lining that radiates your own body heat right back at you.
You know those metallic emergency blankets (also called space blankets) that people wrap themselves in after an accident or after running a marathon? Columbia's Omni-Heat technology uses much the same approach. The lining consists of multiple little dots of a radiant metallic material that reflects your foot's warmth back into the boot instead of absorbing it and drawing the warmth away from your extremities.
And to top it off (or... bottom it off, to be more precise) these boots have an outsole featuring excellent traction that's lightweight and offers a plenty of energy return. The boots are an ideal choice for winter treks, whether you're hiking across miles of woodland terrain or simply plodding across town on a cold wintry morning.
People don't like the Columbia Bugaboot Plus III Omni Cold-Weather Boots ... they love them. A fan named Sean called them "worth every penny if you live somewhere where there is heavy snowfall," while an owner named Joey said they were "absolutely amazing" and sharing that he "tested waterproofness by having on no socks and sticking [my] foot in a bathtub filled with water. Even while fully submerged, my foot was dry."
Most professional gear testers eschewed the bathtub test and instead wore their Columbia boots out into the wilderness. A writer with The Wirecutter said they offer "the best balance of warmth, waterproofing, and walkability," while the Gear Institute review called these boots "comfortable out of the box" and noted the roomy toe box.
Pros: Amazing insulation quality, reliably waterproof, good traction on snow, ice, and varied terrain
Cons: Too warm for use except in winter, rather large and bulky

The best winter work boots
Ever/Business Insider
Why you'll love them: When there's work to be done, the Ever Boots Ultra Dry Insulated Waterproof Work Boots ensure the winter weather won't slow you down. 
A good work boot helps you accomplish your tasks without you even knowing its there. Work boots need to be supportive and protective yet lightweight enough for the long hours required at the construction site, the farm, or the landscaping job. They need to keep your feet warm and dry in the winter, but not be so heavily insulated as to make feet sweat when your body temperature is raised. And of course, work boots need to be tough enough to endure the abuse that comes with the toughest jobs.
The Ever Boots Ultra Dry Insulated Waterproof Work Boots score high marks when tested against every one of the aforementioned standards, and they even have one more attribute worth noting: They look great. While aesthetics might have little effect on how well you get your work done, you might as well choose a work boot that looks good, right?
Made with full grain leather, these boots are a great choice for workers in areas where winter precipitation can be heavy. Beyond that waterproof leather, they have watertight stitches, water-resistant laces, and a seal added along the sole to help make sure no snowmelt, rain, or slush ever soaks through to your feet.
These boots have a solid 4.5-star rating with hundreds of reviews posted on Amazon. One customer calls them "warm and waterproof" while another says they are "sturdy and at a good price."
A gear tester with AllThingsWaterproof.com called the Ever Boots Ultra Dry Insulated Waterproof Work Boots "ideal for construction, landscaping, gardening" and more, while a MyWorkWear.org writer noted the affordable price and the "high quality materials and exceptional workmanship."
Pros: Great price point, reliable waterproofing, classic work boot look
Cons: Sizes run too large, break-in period required

The best boots for extreme winter weather
Wolverine/Business Insider
Why you'll love them: Even when the temperature drops well into the negatives and the snow is blowing in sideways, you can head out with confidence while wearing a pair of Wolverine Vortex BOA Winter Boots. 
The Wolverine Vortex BOA Winter Boots are some seriously heavy-duty footwear. And speaking of heavy, let's get one thing out of the way early: These boots are too cumbersome, both in terms of weight and bulk, for use on long hikes or even for days spent strolling around town in the winter. But for working outdoors, shorter slogs around your property or neighborhood, shoveling snow, snowmobiling, hunting, and for other highly physical activities, they're ideal.
These are superlative boots for extreme winter conditions primarily thanks to their excellent insulation, water-resistance, and their arch and ankle support, which are provided by a molded EVA insole and an upper that almost reaches mid-calf.
But the feature that sets these boots apart from the rest is the BOA lacing system. Rather than pulling the laces tight by hand and then tying a bow to secure the boots, you tighten and secure the wire lacing of the Vortex boots simply by twisting a dial. The laces pull tight evenly and are held secure by the ratchet-locking mechanism of the dial, and simply popping the dial forward about a half inch loosens the laces. This allows you to put on or remove your boots and to tighten or loosen the laces even while you're wearing bulky gloves. Anyone who knows the frustration of fumbling over laces with frost-numbed fingers is nodding right now.
A relative newcomer to the market, these boots don't yet have a lot of reviews from customers. But maybe you'll take it from me: They're excellent boots that are indeed almost strangely easy to tighten and loosen. And yes, I am wearing my pair as I write just to help me connect with the assignment. (No, I'm not kidding. I'm wearing these boots right now ... inside ... at my desk.)
A writer with HuntersHandbook.com praised the BOA lacing system, saying it allows for "a glove-like fit that's easy to adjust on the fly." Multiple gear writers also mention the Vibram Arctic Grip outsole of this and other Wolverine boots, noting its excellent stability in snow, ice, or loose ground.
Pros: Easy to lace up even with gloves on, warm and waterproof, intelligent tread pattern
Cons: Rather heavy and large, expensive compared to other options
