Smartwool Mountaineer Classic Edition Max Cushion Second Cut Crew Socks - Black - XL

While the mesh zones offer breathability, the primary feature is maximum cushioning, making them best suited for cooler to moderate temperatures or high-altitude conditions. For very hot weather, consider a lighter-weight hiking sock.

The socks should fit snugly without being uncomfortably tight. There should be no significant bunching or slipping when worn inside your boots. Refer to Smartwool's sizing chart for specific measurements.

These socks are primarily designed for hiking and trekking due to their maximum cushioning. While they offer comfort, they might be too bulky and thick for the dynamic fit required for most running activities.

Second Cut™ yarn is derived from Smartwool's sock take-back program, where they collect used socks and repurpose the wool fibers into new yarn, promoting sustainability.

Wash after each use, especially after strenuous activity, to maintain hygiene and prevent odor buildup. Follow the care instructions for best results.

Merino wool is naturally temperature-regulating. It helps keep your feet warm in cool conditions and wicks moisture away to help keep them cooler in warmer conditions by facilitating evaporation.

Ensure you have selected the correct size. If the issue persists, the specific fit system may not be ideal for your foot shape. Consider trying a different Smartwool model with a less robust fit system.

Follow the recommended care instructions diligently. Excessive heat or harsh detergents can degrade the cushioning fibers. Ensure socks are fully dry before storage.

Verify that the socks are smoothed out inside your boot with no wrinkles. Ensure your boots fit correctly and are not causing external pressure points. Consider if the thickness of the cushioning is appropriate for your footwear.
