A stable ride for off-road runners.

The Altra men's 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, Altra kept the trail essentials like the sticky Vibram® MegaGrip™ outsole and always-handy GaiterTrap™. As always, signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.

PRC's Take: The robust medial (arch-side) sidewall of the Olympus 4's midsole gives the shoe a distinct asymmetrical look, but more important, this feature coupled with the shoe's broad base delivers a stable ride for the trail runner who typically needs support to align feet, ankles and knees. We're positioning it as a stability shoe for the trails.
