NEVER BEEN WORN Got as a gift years ago but I don’t have a need for these thick socks! Per website: Extra-soft merino lambswool and CoolMax® wrap your foot in warmth and wick away moisture. Stretch nylon/Lycra® elastane blend keeps the sock up and helps keep their shape over time. X-Static fibers fight odor. 78% Merino wool, 15% nylon, 6% polyester with 1% Lycra® spandex. Machine wash and dry.
