Introducing the new Strideline Wool Socks. Why wool? Moisture-wicking - Absorbs the sweat and wicks it away from your skin to the outside of the sock to evaporate. Anti-bacterial - The fibers have anti-bacterial properties that make them odor resistant AND able to be worn multiple times before washing! Soft and lightweight -The fine fibers mean NO itchiness and make them fit easily in shoes Temperature-regulating - Temperature-regulating and insulating properties keep you cool in the summer and warm in the winter. 100% Ecological - Merino sheep are typically shorn once to twice a year – so they automatically grow a new coat. Plus, the shearing process is purely manual labor and causes the animal absolutely no pain. Premium performance - Breathable, antimicrobial, anti-wrinkle, anti-static, stain resistant, flameproof, biodegradable, durable, and quick-drying. Elasticity - Stretches the way you need it to, then returns back to its original shape, preventing sagging and bagging. UV Protection - Absorbs radiation through the entire UV spectrum, naturally protecting against the sun's harmful rays.
