For over 25 years, THORLO™ has been conducting research to develop proprietary fiber blends which enhance wicking and durability. THORLO™ is an industry leader in blended fiber technology, which it incorporates into every sock it makes to assure comfort and satisfaction.

Now, after close collaboration with the US Armed Forces, THORLO has introduced the ultimate sock for Military personnel: the Thorlo Combat Boot sock. Boot-length, constructed with extra padding in the toe, shin and heal areas and made with anti-bacterial, acrylic yarn to promote moisture wicking and fight foot fungus. Equipped with Socklinks to prevent loss and ensure even wear of matched pairs, these socks are easy to maintain, comfortable, and designed to prevent blisters.
