ASSOS earlyWinterSocks_s7- The merino wool of the ASSOS earlyWinterSocks are made of just the right combination of wools that keep your feet warm and dry during the cool Fall and moderate Winter base line training rides. The wool transfers moisture away from your feet so you stay dry and you can maintain the heat inside the sock. The natural anti- l properties prevent odor from settling in. Ideal for temperatures ranging from 42° to 54° F. (6°-12° C)
