Breathe easy. Bringing together smooth Merino Wool feel, next-to-skin fit, flex and fatigue-zapping arch support, and targeted venting — the ultra-lightweight RFL is the sock experience your hard-charging feet have been dying for, lap after lap.

• 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 boundaries. Here's to feeling connected and comfortable in your boots run after run.
• Multi-zone mesh panels improve venting and flexibility, while reducing bulk and pressure points.
• Reinforced Achilles and footbeds improve the comfort, durability and fit of our socks so you can wear them season after season.
• Merino Wool has a natural ability to move heat and moisture, keeping skier's and rider's feet warm and dry.
• Our silky, ultra-lightweight socks are smooth, breathable, and feel like a second skin between your feet and boots.
• 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.
