Banish The Cold with Vasque’s Lost 40 Boots

Cold feet are a killer when you’re outside in the winter.

Whether you’re out for a short hike with the dog, exploring some winter camping, or just making the trek from your car to the ski lodge, the right boots can make even the snowiest days more fun. We’ve been testing Vasque Footwear’s all new Lost 40 Boot ($180) this winter, and it hits all the high notes for extreme cold and snow.

These sturdy boots get their name from famed Lost 40 Scientific and Natural Area in Minnesota. One of the last places in the state to feature first generation Red and White pine growth, in the winter this area is renowned for being cold and inhospitable. With that inspiration, the Lost 40 boots are built with harsh weather and hard use in mind.

The first thing you’ll notice when trying them on, is that the dual construction, mukluk style upper can be a little tough to put on without some practice. The outer boot is a combination of supple, 2mm rough-out leather, and softshell material, that have been waterproofed. Inside that is a 7mm felted wool liner. Together, they make for a snug fit in the ankle while pulling them on and off that a couple of our testers had some trouble with at first. Allow them to warm up on a hike or two though, and the wool liners will slowly mold to your feet, helping you both with fit and warmth.

The toe-box is especially roomy, and lends itself well to wearing thick winter socks – although we got the best results with a midweight sock that left us a little wiggle room for air to circulate. It’s helpful that there are two lacing systems, letting you snug up the upper portion, while leaving your toes and mid-foot unrestricted. We found that especially nice when we wore them for long periods and wanted to loosen them up a little around camp after a long day on our feet.

We hiked, camped, and pedaled fat bikes in the Lost 40 down to -10°F with no issues. The liner’s felted wool is soft and warm. What’s more, the midsole is made from AeroGel, which offers the absolute best warmth-to-weight ratio of any insulating material for boots and apparel. You wouldn’t think this would be important, but after spending long hours in the snow, you will start to lose quite a bit of body heat through your soles. Vasque’s AeroGel solution solves that with ease – we wore them for 18 hours in below zero temperatures and never noticed the cold.


The Lost 40’s are built to withstand extreme weather, and it shows. Lacing eyelets and seams are all double stitched. The felt liners are incredibly sturdy. Outsoles are Vibram’s Icetrek rubber, which gives you excellent grip on snowy conditions. However, it was specifically built for snow and ice, and so is a softer sole – the better to flex and expand for traction. We don’t recommend wearing it regularly on pavement as an around town boot, or out on rocky trails, or you may wear the outsoles out faster than you’d like.

Whether you’re an experienced winter hiker, love to camp out in the extreme cold, or are just building your cold weather kit for some upcoming adventures, the Lost 40’s are your best bet for snowy days.

So you want to take the whole family on an epic ski holiday this winter. First off, it's a great idea. Family ski trips create awesome memories that last a lifetime, and if you get kids into skiing at a young age, they'll soon be out shredding you on the mountain. But taking the whole family on a ski trip not only means a host of ski gear for everyone, but you also have to find the best ski resorts for families.
Family-friendly ski resorts usually have a few common traits. Firstly, they mostly have a load of beginner-friendly terrain. As much as your young ripper may want to send it down the steepest trail, they need more time on easier groomers before they hit the steep slopes. Suitable bunny slopes and loads of green and blue trails are a must. And then there are the lessons. Seriously, outsource the teaching. Not only will it make your kid a better skier, but you'll get more time on the slopes, and it will avoid too many tears and tantrums — from both sides. On top of these, there are added extras like free hot chocolate, sleigh rides, ice skating, and more, that can all be found in these, the best ski resorts for families.

Ski season is in full swing now, and your holiday may be just around the corner. You've found the perfect beginner resort or some steep and deep terrain, and you've even upgraded your ski gear for the season. But what about your skis? Will those ex-rental bad boys still rock it for you now that you've mastered your turns, or would you rather be seen rocking a set of quality skis to complete the look?

It's not just aesthetic, either. Sure, in the hands of a pro, your shaky old skis could be made to look pretty good, but if you're serious about progression — or just about genuinely enjoying your time on the slopes — you need the right set of skis. These come in all forms — twin tips, powder skis, race skis, beginner, intermediate, and advanced — but what's important is that whatever set you choose should be quality. Now more than ever, the ski market feels like a level playing field, with brands all vying to be number one, but which brands are quality, and which should you avoid? Well, here's our list of the top ski brands this winter.

It can be tempting — when the snow is falling and outside temperatures drop sub-zero — to get yourself comfortable on the sofa with a good book or a new film. But the winter months provide some of the best outdoor experiences of the year. With spectacular sunrises and sunsets, snowy scenes and quieter trails, it's not just skiing and snowboarding that you can do in winter in the US.

But winter requires a whole different set of gear to stay safe and warm and to enjoy your days out on the trail. Along with knowing how to navigate on the trail in the winter, understanding the dangers of avalanches — if they apply to where you hike — or knowing what to do if you get caught out in a storm, having the right winter gear is a seasonal essential. This list of eleven items isn't a comprehensive winter packing list, but it does contain some winter essentials and a few items that will make your winter days that bit better.
