The updated version of Altra's original trail shoe features a trimmed down layer that offers added flexibility and comfort and a simplified lacing system for improved micro-adjustment. Like all previous versions, the Lone Peak 4.5 includes all of the Altra trail shoe must-haves like StoneGuard™, MaxTrac™, Balanced Cushioning and the FootShape™ toe box. To top off the update, the midsole foam formula has been tweaked just enough to give you a more resilient feel underfoot.

BALANCED CUSHIONING: Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your run.

FOOTSHAPE™ TOE BOX: Allows your toes to relax and spread out naturally for more comfort and stability.

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.

MAXTRAC™: A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss.
