The Lone Peak 4 is a fresh take on Altra's original trail shoe with several significant updates. The new upper will include the same integrated tongue as the previous version but now with static webbing for better cinching ability, a flexible strap overlay for a roomier forefoot fit and a sandpaper textured toe cap. In addition, breathability is improved by way of draining mesh in the heel and forefoot and the decoupled nature of the TrailClaw™, as well as multi-directional, carved lugs for improves traction and reduced weight. To top off this already awesome shoe the StoneGuard™ is completely updated to resemble the skeletal structure of a foot for better performance and dynamic flexibility.
