In Denmark, where temperatures can dip down to -20 degrees below zero (F), they know a thing or two about staying cozy. Short of rolling yourself up in a bearskin rug, their best remedy for a Scandinavian-level chill is to slip your pups into Glerups. Each pair is handcrafted from a mix of Merino and Gotland wool, a combo that naturally pulls moisture and excess heat away from your feet, so they stay pleasantly warm and dry no matter where you wear ‘em. Add grippy rubber soles, and they’re really pushing the boundaries of where slippers can go. So whether you’re headed out to the campfire or staying in by the hearth, do like the Danes do when you kick your boots off—Glerup up.
