Burly trail runners that promote a natural running gait. The ample toe box allows your toes to spread and splay naturally during your foot strike and zero drop promotes a natural stride. The Superior 4.5 has an updated upper for increased breathability and drainage. Great for training, racing and a great option for runners with high-volume feet.

  • Breathable mesh upper has reinforced overlays for durability.
  • Removable StoneGuard adds protection.
  • Lightweight Quantic™ midsole is flexible and supportive.
  • MaxTrac™ rubber outsole with directional lugs for off-road traction.
  • Gaiter trap helps to secure a range of trail running gaiters (sold separately)
