Can you hear the crunch of ice under your boots? Is that the smell of hot cocoa wafting from your mug? It can only mean one thing — winter is here. Whether you’re giddy about the cold season like we are (hurray, dog skijoring!) or you plan to hibernate until the warmth returns, you can count on warm winter boots to keep your feet feeling happy until spring.

Of course, winter weather feels pretty different depending on your latitude and longitude. Here at KEEN HQ in the Pacific Northwest, winter means foggy mornings and icy front steps. In other parts of the world, it could mean six feet of snow or a 60-degree day. That’s exactly why we make winter boots with different levels of insulation to suit different climates. From warm to warmer to warmest styles, read on to find out which winter boots are right for you.

Meet Our KEEN.WARM Insulation

When it comes to keeping your feet warm, insulation is everything. Our signature KEEN.WARM insulation is extremely lightweight for the amount of warmth it provides, and it retains its insulating ability even when damp. We offer boots with 100g - 400g of insulation to keep toes toasty through every cold-weather outing, from rainy-day walks to epic snowy adventures.
