RU ULTRALIGHT SERIES

Building upon the innovation of our original Ru Series running socks, the Ru UltraLight Series running socks feature a lighter construction and mesh for maximum cool comfort making it perfect for warmer months or climate.

Starting from the bottom, we added extra cushioning where you need it the most on the front and heel parts of the running sock to keep you comfortable over long distances. Tight elastic through the middle portion provides extra planar arch support preventing soreness and fatigue as you cruise. In addition, extra padding on the instep of the running sock protects your metatarsal bones from friction and pressure from your shoe that may result in bruising after long runs.

As you heat up into your workout, our innovative CoolPlus construction quickly dissipates moisture by channeling it out of the running sock. Mesh uppers allow for further breathability.

Although often overlooked, running socks are constantly in contact with your feet. We at Thirty48 recognize the importance of starting with a great foundation for an even greater workout.

Ultra Super Lightweight High Tech Running Socks for Men and Women - Best for all varieties of exercise and sports and everyday wear. Low cut style fits perfectly with any running, cross training, tennis, soccer, etc. shoes/cleats/trainers. Convenient pull tab allows for easy wear off/on and ensures that the sock stays in place through the most vigorous exercise, reducing blister causing friction and abrasion.

Anatomically Targeted Cushioning - Designed with foot anatomy and biology in mind, denser cushioning provides extra relief to pads and heel while better supporting the Achilles Tendon and metatarsals to help prevent bruising and pain in high impact areas of the foot.

Seamless Toe Closure - Seamless socks are designed to reduce the irritation that often causes blisters and soreness. The shape of the sock with its seamless toe closure was engineered specifically to maximize comfort for each individual foot in extreme condition and daily use.

High Tech Moisture Wicking and Dissipating Fabric – A proprietary blend of 50% Nylon, 14% Lycra Spandex, 23% Wick Poly, 13% Cotton channels moisture and sweat away from surface of the skin keeping feet cooler and drier. Less moisture helps prevent the growth of bacteria and fungus which can cause odor and health problems.
