Designed for logging long, fast miles, the Transistor FS connects your foot to the shoe while connecting you to the trail.

The Transistor FS is about connecting the runner to the trail in a whole new way. Using the patent pending FootSync Fit System, the runner is closer to the ground as the shoe morphs to their individual foot shape. This is achieved without sacrificing cushioning. The result is an extremely light trail shoe that offers unsurpassed control, seamlessly connecting to the foot and to the terrain.
