Yes, they look funky, chunky and thoroughly fun. But these socks have a serious side that, figuratively speaking, will really tickle your feet. They're made mostly of soft, moisture-wicking, naturally odor-resistant Merino wool that’s utterly itch free and machine washable. Add in SmartWool's cushioning technology, supportive arch construction and no-bunch toes, and you've got socks that feel mighty sweet on your feet. Knee-length.
