RU LIGHT SERIES

Building upon the innovation of our original Ru Series running socks, the Ru Light 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.
