RU SERIES

Purposefully designed with high tech features, our original Ru Series running socks take into account the experience of real runners and targets common gripes like annoying stickiness, discomfort caused by shoe lacing.

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 Coolmax 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.
