Simms Mid Calf Liner Socks are designed to provide comfort and performance during your fishing adventures. Made from a technical blend of 64% polypropylene, 33% nylon and 3% Lycra Spandex, these socks are lightweight, breathable and moisture-wicking to keep your feet dry in all conditions. The heel and toe are reinforced with polypropylene yarn for greater durability, while high-wear areas benefit from nylon yarns to prolong their life. Their mid-calf height guarantees optimum coverage, whether you wear them alone for wet-wading in summer or layered with standard socks in colder weather. Ready for all your fishing outings, they provide comfort and protection all day long.
