The updated version of our 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 trail run.
