Edinburgh-based Deputy Editor Maxine Eggenberger swears by a shearling lining for keeping toasty in the chilly northern hemisphere. “I stumbled on this cold-weather trick by accident. I’d had my eye on a pair of boots for months, but when they eventually went into the sale, the only pair in stock was a size up from the one I’d usually buy,” Eggenberger explains. “I ordered them anyway, and when I proceeded to complain that they were too big, my grandma gave me a pair of sheepskin liners from a pair of her boots to offset the extra room inside. And boy were they toasty. Turns out that sheepskin insoles are a thing all their own, and now, I purposely buy my boots a size up to accommodate them.”
