No, it’s not a mirage – that’s just the magical, moisture-wicking properties of Merino Wool you’re seeing. Ultra-Lightweight and undeniably tough, this long-lasting knit is guaranteed to take you places you never thought you'd reach. Men's micro crew socks average 8.5 in. from heel to cuff - expect them to rise about 6 in. above a running sneaker. A performance fit means no slipping, no bunching, no blisters. Here's to focusing on your run and not your feet. Runners enjoy Merino Wool's ability to dry quickly and move excess heat and moisture away from feet. Our lowest profile, ultra-lightweight yarns create zero bulk, zero itch socks that feel like a second skin. Arch support alleviates foot fatigue and bunching for long-running comfort with zero slippage. We close every toe seam using our True Seamless™ Toe technology for an ultra smooth, undetectable feel. 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.
