There's no such thing as bad weather, just bad gear, right?! Well with the brand new Altra Lone Peak 4 RSM you'll have no excuse. Made for rain, snow, and mud (RSM), this shoe is ready to tackle the elements. As part of the Altra All-Weather Series (AWS) the upper is made of eVent. eVent is 100% waterproof and offers market leading breathability, delivering maximum comfort and protection in the widest range of conditions. In addition, it has a reinforced toe cap, refreshed mountain design and 4-Point GaiterTrap. And the updated MaxTrac outsole with multi-directional lugs and prominent TrailClaw offer enhanced traction on gnarly terrain. A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss. This unique tread pattern positions lugs beneath your metatarsals for incredible traction in steep climbs and descents. Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe. Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents. Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run. The Fit4Her technology means we customize every women's shoe to the unique anatomy of the female foot.
