• Men's over the calf socks average 17 in. from heel to cuff - expect them to cover the leg to just below the knee.
• A performance fit means no slipping, no bunching, no blisters for peak hiking comfort.
• We close every toe seam using our True Seamless™ Toe technology for an ultra smooth, undetectable feel.
• Reinforced footbed and Achilles cushion improves the comfort of our socks and helps them last longer.
• Merino Wool is at home on the trail, naturally moving moisture to keep feet fresh and dry in all weather.
• Our warmest socks - heavyweight socks trap heat, transfer moisture, and provide steady comfort on the coldest treks.
• The “still” in Still Made in Vermont, USA is personal. We knit all our socks at our VT-based Mills - we can't imagine it any other way.
• Unconditionally Guaranteed for Life - if these aren’t the longest lasting socks you’ve ever owned, return them for another pair.
