Ready for any weather you choose to run in and through, the updated Altra Lone Peak 4 Low RSM trail-running shoes for women have waterproof eVent® uppers to handle rain, snow or mud (RSM) with ease.

  • Features

    • eVent is extremely breathable and waterproof at once; billions of tiny pores in the material help these shoes breathe in any condition
    • MaxTrac™ outsoles with a multidirectional lug pattern provide excellent traction
    • Lightweight, skeletal Stoneguard™ plates protect against rocks
    • GaiterTrap™ hook-and-loop tabs secure your gaiters (not included) to your trail shoes to keep dirt and debris out
    • Altra signature FootShape™ toe boxes allow your toes to relax and spread out naturally while your big toe remains in a straight position
    • Balanced cushioning places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run
    • Fit4Her™ means Altra designs shoes around the shape of the female foot—narrower heel and midfoot, higher instep, longer arch and unique metatarsal spacing as compared to men's
    • 5 mm contour footbeds
    • Stack height of 25 mm offers plenty of cush underfoot for long miles
    • Granted the APMA Seal of Acceptance, which the American Podiatric Medical Association awards to footwear they find promotes good foot health

    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.
