RX6 Lightweight Tab (Black) Runner Socks

Regular price $12.00

The RX6 black lightweight tab running sock is made from REPREVE, a post-consumer performance fiber made from recycled materials (like plastic bottles). REPREVE is one of the most environmentally friendly fabrics in the world, offering performance-enhancing technologies that keep your feet cool and dry with moisture-wicking materials that also provide thermal and UV protection. The RX6 black lightweight running tab sock has a clean design packed with 6 points of technology, providing you with a lightweight body, rebound cushion, and elongated arch support for a fit that ensures no blisters.

- Seamless Toe: When you’re working hard, the last thing you need is to be distracted by lumps and bumps in your shoe. Our seamless toe socks allow you to stay focused on your workouts without any distractions.

- Moisture Management: The fabrics from which we’ve designed the RX6 black lightweight running tab sock keep your feet cool and dry no matter how long your run or exercise routine lasts, eliminating another distraction that could otherwise hinder your performance.

- Select Cushion at Points of Impact: When you enjoy running on rough terrain, you need as much protection as you can get. Your shoes can only do so much, so to offer an extra layer of protection, we’ve engineered this sock with light cushioning on the places your feet experience the most impact.

- Y-Heel & Y-Toe: The RX6 black lightweight running tab sock features a Y-heel and Y-toe to keep the material from bunching up inside your shoe, which can feel distracting and uncomfortable.

- Stay Up Tab Back: If your workouts are vigorous, you want to make sure your socks stay in place. That’s why we’ve included a Stay Up Tab on the back of the sock, which comes slightly above the opening of the shoe and keeps the material in place.

- Extended 360-Degree Arch Support: For an even more superior fit, we’ve included extended arch support in our design. It offers a light compression that hugs the center of your foot, giving you all the support you need as you run.
