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.
