Warm socks made of polyamide, acrylic and an admixture of Merino wool, which is unusually thin but very warm and elastic.
Merino wool keeps you warm even when wet.
The socks have a shin protector reinforced with terry cloth, an ankle stabilizer is an elastic band around the ankle that prevents injuries to tendons and muscles in this area, and an elastic metatarsal support that does not restrict freedom of movement.
