Under Armour® All-Season Boot Socks for Men earn their name with a versatile design that's big on comfort and performance. These men's wool socks sport exclusive ColdGear® Charged wool, for the soft comfort of classic wool and highly engineered fibers that dry faster for a cleaner feeling and less odor. Wool also brings natural thermal regulation, providing airflow in warmer temperatures and heat retention in the cold. ArmourDry® material wicks moisture to speed evaporation. The Light Cushion Leg reduces bulk and delivers flexibility. A high-density selective-cushion foot delivers responsive support and impact absorption. Unique left/right engineering gives a true anatomical fit. True Seamless Toe construction reduces irritation, and dynamic arch support reduces foot fatigue. These Under Armour boot socks even boast ArmourBlock® odor-reducing technology to keep these men's boot socks fresher, longer. 39% Acrylic/39% Merino Wool/17% Polyester/4% Spandex/1% Nylon.
