Smartwool | Run Targeted Cushion Low Ankle Socks

The Ultimate High-Performance Blister Barrier

Whether you’re logging morning loops around Point Pleasant Park or crushing a tempo run on the Chain of Lakes Trail, your socks are the absolute line of defense between your feet and your footwear. The Smartwool Performance Run Targeted Cushion Low Ankle Socks are engineered to completely eliminate the friction, slipping, and moisture buildup that cause race-ruining blisters. By combining the natural thermoregulating power of Merino wool with advanced fit technology, these socks stay put so you can focus entirely on your pace.

Smartwool’s 4 Degree™ Elite Fit system uses two elastic bands for greater stretch and recovery, locking the sock securely to your foot so it won't bunch up at the toes or twist mid-stride. Strategically placed targeted cushioning is mapped directly to the high-impact zones under the ball and heel of your foot, giving you essential shock absorption without adding unnecessary bulk inside your running shoes. Built with Indestructawool™ technology for maximum durability and featuring body-mapped mesh zones for optimal ventilation, these socks handle hot, humid East Coast summers and damp morning mist with ease.

Key Features

• Indestructawool™ Technology: A specialized construction method that reinforces high-wear zones for extended durability, helping your socks outlast your longest training cycles.
• 4 Degree™ Elite Fit System: A performance-oriented design with strategic stretch zones that keeps the sock firmly anchored in place, preventing shifting and friction.
• Targeted Underfoot Cushioning: High-density impact protection concentrated precisely at the ball and heel of the foot, maintaining a low, responsive profile.
• Mesh Ventilation Zones: Body-mapped mesh panels allow heat and moisture to escape quickly, keeping your feet dry and cool.
• Virtually Seamless™ Toe: A completely flat knit toe seam removes the primary cause of chafing, hotspots, and pressure points in the toe box.
• Integrated Achilles Tab: A slight rise at the back heel protects against shoe collar rubbing and ensures the sock never slides down into your footwear.
