When you slip your feet into these soft shearing slippers, you'll undestand exactly why they are one of our top sellers.. Unlike similar-looking imitations, our men's slippers are made of superior sheepskin. Known as one of nature's best insulators, shearing draws away moisture so your feet stay warmer on chilly mornings. Best of all, the shearing wraps completely around your foot so you feel nothing but soft, warm fleece against your skin.
