The lightweight speed-hiking boot with Missiongrip. Missiongrip™ rubber adds traction while lugs bite into soft trails. The Swiss-engineered FlexLock system means laces can be tied traditionally or with a single pull. A 360° mudguard protects and the Speedboard™ provides propulsion and stability. Tongue straps secure laces and Zero-Gravity CloudTec® ensures cushioned landings. Terrain proof. Element proof. Excuse proof. The first On speed-hiking boot is built for traction, pace and protection in all conditions. And it's up to 35% lighter than competitors.
