In it for the long run? So are we. With a 3.5" inseam and compressive fit that stays put, the Run Short was designed with your speed in mind. Plus, since they're made from recycled post-consumer water bottles, they help eliminate waste from the environment — so you can focus on other stuff, like improving that mile time. Recycled and recyclable — when you’re finished with this item (a long, long time from now), recycle it with ReGirlfriend.
