Designed for hiking, backpacking and thru-hiking on cold, wet days, the women's Altra Lone Peak 4 Mid RSM boots feature waterproof, breathable eVent® uppers to seal out rain, snow and mud.

  • Features

    • eVent is insanely breathable and waterproof at once; billions of tiny pores in the material means it breathes in any condition
    • Fit4Her™ means Altra designs shoes around the unique shape of the female foot—narrower heel and midfoot, higher instep, longer arch and unique metatarsal spacing
    • Every Altra shoe features a ZeroDrop™ platform that places the heel and forefoot the same distance from the ground, which encourages low-impact landings
    • ZeroDrop platform also helps naturally align the feet, back and body posture
    • Stack height of 25mm offers plenty of cush underfoot for long miles
    • Altra's signature FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position
    • This reduces overpronation, enhances stability and creates a powerful toe-off to maximize running or speed-hiking performance
    • GaiterTrap™ hook-and-loop tab secures your gaiters (sold separately) to your trail shoes to keep dirt and debris out
    • DuraTread rubber outsoles feature an improved TrailClaw™ design and lug pattern for maximum traction
    • Granted the APMA Seal of Acceptance, which the American Podiatric Medical Association awards to footwear they find promotes good foot health
    • Altra indicates these shoes fit true to size

    Sizing Notes

    Altra’s unique FootShape™ toe box and Balanced Cushioning™ platform create a natural fit that follows the shape of your foot, instead of squeezing your toes and raising your heel. Your toes have room to spread out and your foot remains in a flat, natural position. When fitting, be sure to allow a full thumb’s width in front of your toes. If your feet are used to cramped toe boxes, Altra shoes may feel a little big at first. Give your toes some time to get used to the newfound wiggle room.



    IS THIS SHOE TRUE TO SIZE? The product Features above will provide a suggestion if Altra advises you to size up or down in this particular shoe. If no such note exists, please order your regular size.
