Bridgedale Heel Fit Midweight Ski Sock - Ski boots don't always fit just right. They can rub your feet and legs, causing blisters, and sometimes your feet stay cold all day. Bridgedale has the answer. The Women's Heel Fit Midweight Ski Sock provides cushioning where you need it; the heels, ankles, and shins. The anatomical design gives you midweight warmth with less bulk, and mapped heel cushioning takes care of narrow heels to prevent slipping and blisters.
