This sock is as hard working and tenacious as the Nordic skiers it was designed to perform for. This version of our Nordic Boot sock has a dampening layer of cushioning along the bottom of the foot that adds extra support and comfort. Fine gauge Merino Wool provides consistent warmth and breathability. And since Merino Wool is naturally antimicrobial this sock repels bacteria and odor. Ideal for vigorous winter excursions like snow shoeing and cross-country skiing. Simply put, it's a great winter sock for any activity. Still made in Vermont. Guaranteed for life.
