Introducing Donatello, Norfolk's first double-layer merino wool outdoor sock. It pairs our favorite outdoor sock material, merino wool, on the outside with a smooth, soft PROLEN® inner layer that reduces friction between your skin and the sock to help prevent rubbing and blisters.
Most blisters are caused by friction when your feet get hot and sweaty. PROLEN® works as a dry layer against your skin, passing moisture to the outer merino layer so your feet stay cool and dry.
An invisible flat toe seam minimizes friction across the toes, making these socks the perfect partner for any hiking boot. Twin ankle and arch support, a fully cushioned footbed, and ergonomically shaped left and right feet make Donatello a must for any serious hiker.
The low-friction, moisture-wicking double layer and low-profile flat toe seam also make it a comfortable choice for people with diabetes or sensitive feet.
