The Defeet Wooleator Tall 5 inch Socks are similar to the Aireator socks, but made from merino wool for additional plush warmth in the depths of winter. Designed to fit like a thin summer sock whilst having the insulating properties commonly associated with a thick winter alternative, these socks are sure to keep your feet warm without overheating and provide a modern cuff height for an on-trend aesthetic.
