The Elka is as hard working and tenacious as the Nordic skiers this sock is designed for. A layer of cushioning along the bottom of the foot that adds extra support and comfort. Fine gauge Merino Wool provides consistent warmth and breathability. This is a perfect sock for vigorous winter excursions, from snowshoeing to cross country skiing. And since Merino Wool is naturally antimicrobial this sock repels bacteria and odor. Still made in Vermont. Guaranteed for life.
