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 eVent® upper 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 Duratread™ outsole with multi-directional lugs and prominent TrailClaw™ offer enhanced traction on gnarly terrain.

• Upper
  • eVent® Fabrics
  • GaiterTrap™: Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe.
• Midsole
  • Dual Layer EVA / A-Bound™: Environmentally friendly, this energy-return compound is made of recycled materials. Offering extra protection, this unique layer sits directly under the foot to return energy back into each stride. It reduces the impact of hard surfaces while still maintaining ground feedback. Traditional running shoe foam compresses 70-90% while A-Bound™ compresses 2-3x less so it won't deform over time.
  • Sandwiched StoneGuard™ Rock Protection: Sandwiched near the foot, between the A-Bound™ and the midsole, the StoneGuard™ offers flexible protection. This multi-sectional layer deflects rocks into the midsole for a smoother, more stable ride.
  • Insole: 5 mm Contour Footbed
• Outsole
  • MaxTrac™ Rubber: A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss.
  • TrailClaw™: Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
  • DuraTread™: Durable outsole rubber made to last long and offer great grip on both tame and technical terrain.
• Heel
  • N/A
• Forefoot
  • Moderate Cushioning
  • Footshape™ Toe Box: Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents.
  • Fit4Herr™: The Fit4Her™ technology means Altra customizes every women's shoe to the unique anatomy of the female foot.
• Offset
  • Fully Cushioned Zero Drop™ Platform: Every Altra running shoe features a fully cushioned Zero Drop™ platform that places the heel and forefoot at the same distance from the ground. This natural balance aligns the feet, back and body posture for less impact. It also strengthens the Achilles and lower calf muscles that have been weakened over a lifetime of running on elevated heels.
