45NRTH Stripe Midweight Knee Wool Sock - Black Medium. Our knee-high midweight socks are warm enough to keep the cold at bay but won’t add bulk under your Naughtvind bibs. Knee-high coverage eliminates gaps in layers. The Merino wool blend wicks moisture away from your feet to keep them warm and dry. Wear them on their own on cold days or layer them with our lightweight socks for a vapor barrier in deep cold. — we think they're the best socks for cycling in winter period.
