The Altra Olympus 4 is the Olympus like you’ve never seen it before. Inside the overall new look, you’ll find everything you loved about previous versions and more. This max cushion trail shoe features an improved premium tongue for enhanced comfort and a more locked-in feel. The engineered mesh upper is breathable and durable for those long, hot trail days and the InnerFlex™ midsole offers increased flexibility and performance. To top it off, we kept the trail essentials like the sticky Vibram® MegaGrip™ outsole and always-handy GaiterTrap™.
