SIMMS MID CALF SOCK LINER - Slip into the lightweight, moisture-wicking sock liner that's perfect for summer wet-wading or layering with standard socks for extra warmth on chilly days. The body, heel, and toe boxes are knitted with a polypro yarn that wicks moisture and is highly breathable. Nylon yarns are knitted into high-wear areas for enhanced durability. Mid-calf height. Wear these under your heavier sock for extra protection. Also a favorite for wearing under your flats boots, protecting your feet from small sand particles and debris that may creep into your boots when wading salt flats. Made in USA
