Built for long shifts, fast movement, and all-day comfort — with breathable mesh, targeted cushioning, arch support, and Silver Lined™ odor control.
The Covert Threads Red Line Tab Sock was designed as part of our First Responders Line: To Serve and Protect, but its comfort, durability, and performance make it a strong choice for anyone who spends long hours on their feet.
Made with moisture-wicking polypropylene, Sta-Cool fibers, Spandex Lycra compression, and top-of-the-line Silver Lined™ Fabric, this low-cut tab sock helps keep feet dry, cool, supported, and fresher throughout the day. Whether you’re on duty, at the gym, on the move, or working long shifts, the Red Line Tab Sock is built to reduce slipping, bunching, chafing, and odor.
A protective heel tab helps reduce rubbing at the back of the shoe, while built-in arch support delivers a secure, stay-put fit. Cushioned Strike Zones™ add comfort where your feet take the most impact, and a thin mesh instep increases airflow for breathable wear in demanding conditions.
