"Named after one of Vermont's most photogenic lakes, the Darn Tough Willoughby Micro Crew Lightweight Hiking Socks for Men have you comfortably exploring majestic scenery while expressing some playful personality to boot. These lightweight men's socks support natural breathability and flexible comfort for warm-weather treks without fear of the dreaded swamp-foot that can lead to blisters. Climate-controlling merino wool naturally moves moisture to keep feet fresh and dry in all weather. Soft terry loops provide underfoot comfort with targeted Achilles reinforcement for added durability.

A performance fit locks the socks in place to prevent slipping and bunching. True Seamless Toe technology closes every toe seam for an ultra-smooth, undetectable finish.
