The North Face Chilkat 400 II Winter Hiking Boots Review

TNF Chilkat 400 v2

The North Face Chilkat 400 II is an insulated waterproof/breathable winter hiking boot rated to -40F/-40C. Available for both men and women, these boots come up to mid-calf for maximum heat retention and feature metal lacing hardware for durability, a gaiter ring above the toes, and a ridged heel counter that helps keep snowshoe straps securely fastened. A pronounced forefoot rocker makes them great for hiking and they have enough of an arch under the sole to run a gaiter strap if you wear high gaiters in winter.

But what sets the Chilkat 400’s II apart from other insulated boots is their warmth. They are exceptionally warm for all-day comfort in freezing temperatures, without being ungainly for winter hiking  However, sizing runs about ONE FULL SIZE SMALL. Wide sizes are not available and while the toe box is roomy, it’s not as high volume as other brands like KEEN and Columbia.

The North Face Chilkat 400 II is the kind of insulated boot you want for long winter hikes when your trips start before the sun comes up and end after it goes down. Rated to -40F/-40C, they are insulated with 400g Heatseeker insulation, which is a highly compressible synthetic insulation similar to Thinsulate and used in many of The North Face’s products. These Chilkats 400 II are also mid-calf height, which traps more body heat than mid-ankle height insulated winter boots which cover less of your lower leg (See: 200g vs 400g Insulated Winter Hiking Boots).

The upper cuff and tongue are covered with a soft fleecy synthetic liner while the exterior is covered in leather with ballistic nylon in high flex areas. The bottom half of the boot has a wide wraparound rand that provides great toe and side protection while helping to ensure that the boots stay watertight for the long haul. While that makes them look a little like PacBoots, (See: The Problem with PacBoots), they are anything but, with an aggressively rockered and curved sole which makes it easy to walk and hike in them.

The Chilkat 400 II’s have a rubber outsole and beefy outsoles that provide great traction on a variety of surfaces including slush, dry snow, wet snow, and wet leaves. I’ve been hiking and snowshoeing with them the past several weeks and they grip well on all of those surfaces.

The North Face includes a thermal insole with the Chilkat 400 II, which is covered in felt for warmth but does not have a reflective aluminum coating. The insole is glued inside the boots although you can peel them out if you want to replace them. When worn, the boots have enough internal volume that you can replace the insole with one that has more arch and heel support. I wear mine with Superfeet’s merinoGrey insoles which are wool-covered for warmth but have a much more aggressive arch to prevent plantar fasciitis.

The Chilkat 400’s have an exaggerated front toe kick for toe protection and a reinforced heel counter to lock your heel in place and prevent pronation. Ridges on the back of the heel help keep snowshoe, crampon, or microspike straps from slipping down and off which is a real plus for more technical winter hikes from traction aids are required. The boots also have enough of a mid-sole arch that you can wear gaiters with a thick stirrup strap, like OR Crocodiles, without worrying about wearing them down from excessive surface abrasion.

There’s minimal time to break-in The North Face Chilkat 400’s which are soft and pliant out of the box. The only difficulty you’re like to experience with them is choosing the right model because The North Face names many of their boots with very similar variants on the same Chilkat product name. (Note: The Chilkat 400’s women’s model is called The North Face Chilkat 400, not the Chilkat 400 II)

Comparable 400g (-40F/-40C) Insulated Winter Hiking Boots


The North Face Chilkat 400 II insulated winter boots are ideal for men and women who want or need very warm winter hiking footwear. Rated to -40F/-40C, their high mid-calf height helps lock in warmth while a fleece-lined collar and gusseted tongue provide both comfort and additional warmth. Their thick soles provide excellent insulation from the cold ground while durable metal hardware ensures trouble-free use and long life. The sizing runs a full size small though, so size up. Amazingly, these boots are wearable out of the box and require virtually no break-in period.
