THORLO Men's Anti-Fatigue Military Over Calf Socks, Size L (EU 43-47), Olive Drab

On long marches, ruck runs, or extended shifts in the field, every step counts. The THORLO Anti-Fatigue Military Over Calf sock is built for soldiers, hikers, and outdoor professionals who demand maximum cushioning and blister protection. Its proprietary THOR•LON® acrylic blend wicks moisture, while the dense padding in the heel, ball, and toe absorbs impact and reduces fatigue. The over-calf length stays up without binding, and the seamless toe eliminates friction. In olive drab, it meets uniform requirements and withstands repeated washings.

Why choose it

Thorlo's anti-fatigue technology is engineered to reduce the stress of high-impact activities. The dense, resilient padding absorbs shock and returns energy, helping you stay on your feet longer. The moisture-wicking fibers keep feet dry, preventing hot spots and blisters even in hot, humid conditions. The over-calf design protects the lower leg from boot chafing and debris, while the arch support provides a secure, stable fit.

Ideal use cases

• Military training and field operations
• Long-distance hiking and backpacking
• Rucking and weighted marches
• Extended shifts on your feet (security, law enforcement, EMS)
• Cold-weather outdoor work

Good to know

THORLO socks are made in the USA and are known for their durability. Machine wash warm, tumble dry low. Avoid fabric softeners, which can reduce wicking performance. Order your normal shoe size; the sock is designed to fit snugly without compression.
