Women's Altra Olympus 7 - White Smoke/Winter Twig A plush, light, and soft midsole combines with an intensely grippy Vibram® outsole for a shoe that’s designed to go the distance. All terrain. All day. The Olympus 7 is crafted with an updated Altra EGO™ MAX midsole foam that’s 15% lighter and 10% softer than the previous version to keep you feeling fresh, mile after mile. With a Vibram® Megagrip outsole with TractionLug™, you’ve got fierce grip with adaptative traction and stability on wet or dry terrain. Keep it comfortable with a plusher tongue, integrated comfort collar, and breathable engineered mesh upper. Plus, new molded TPU overlays are designed to improve your protection and durability. It’s got our roomiest toe box to help your toes move more freely with space through the midfoot, and zero drop for natural movement. Get the comfort and confidence you need for long training days and even longer ultra trail races. Lighter. Softer. Grippier. But still tough AF.
