Introducing the striker® Bolt. It's everything you loved in the original, now built on the all-new terra force® next™ platform. We started with our own striker Bolt outsole to ensure maximum surface contact and grip, added the proven Vibram® spe midsole for maximum energy return and incorporated a bi-fit™ board for reduced weight and foot fatigue. The result is reliable comfort, performance and durability, no matter how grueling the shift.
