The Boulder Medium Weight is a medium-weight traditional hiking sock, ideal for colder temperatures. It features our outer plaiting construction, which surrounds the softer body yarns with more durable stretch yarns for better insulation and improved longevity. Top-to-toe full-density padding cushions the instep and entire leg shaft when wearing heavy boots, and 100% US-grown merino wool provides exceptional insulation, even when wet with snow or perspiration.
