Smartwool | Run Targeted Cushion Low Ankle Socks – Nightfall Blue

Focused Protection for High-Output Miles

Whether you are running technical singletrack or clocking fast training miles on the road, your feet deserve protection without the weight of a heavy, bulky sock. The Smartwool Run Targeted Cushion Low Ankle Socks in Nightfall Blue are built precisely for athletes who need a fast, nimble feel underfoot, combined with strategic impact absorption exactly where the foot hits the ground.

Crafted with premium, responsibly sourced Merino wool, these socks excel at temperature regulation and natural odour resistance. The targeted cushioning maps high-density padding strictly under the heel and the ball of the foot, protecting your joints during heavy descents while leaving the rest of the sock ultra-thin and highly breathable. Engineered with the 4 Degree™ Elite Fit System and a secure Achilles heel tab, they lock firmly to your foot to eliminate friction, bunching, and blisters from the first mile to the last.

Key Features

• Targeted Cushioning: Features focused padding under the heel and the ball of the foot to absorb repetitive shock, keeping the rest of the sock low-bulk.
• 4 Degree™ Elite Fit System: A high-performance, dialed-in fit that utilizes elastic flex zones at the ankle to ensure the sock perfectly wraps your foot and never slips.
• Indestructawool™ Technology: A patent-pending, heavy-duty construction method that dramatically reinforces high-wear areas for ultimate longevity.
• Shred Shield™ Toe Protection: Strategically reinforces the front of the toe box to prevent holes caused by toenail friction during steep descents.
• Virtually Seamless™ Toe: An ultra-smooth, flat toe seam closure that eliminates rubbing, chafing, and pressure points inside the toe box.
• Achilles Heel Tab: An integrated rear tab that keeps the sock from sliding into your footwear while protecting your heel from stiff collar friction.

• The Effort: Trail running, high-mileage road training, fast-packing, and high-intensity workouts.
