Altra Men's Superior 4.5

1 left in Johannesburg


Lightweight. Fast. Grippy. Fast. Responsive. Fast. There are many words to describe the speedy Superior 4.5. The Quantic™ midsole offers a lightweight yet responsive ride for high-speed trail days. The MaxTrac™ outsole and multi-directional lug pattern brings grippy traction to any terrain. The improved upper brings better breathability and durability. And finally, the removable StoneGuard™ offers lightweight rock protection for when the trails get extra rugged.


  • FOOTSHAPE™ TOE BOX: Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents.
  • BALANCED CUSHIONING™ PLATFORM: Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run.
  • GAITERTRAP™: Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe.
  • TRAILCLAW™: Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
  • QUANTIC: New midsole cushioning with a perfect blend of plush, responsive cushion and a lightweight ride.
