Stack height: 33mm
Outsole: Vibram® MegaGrip™
The Altra Olympus 3.5 keeps the favourite attributes of the previous version with key updates.
The Olympus 3.5 receives minor updates to the upper and it features a new, more durable upper fabric pattern, but otherwise retains the same attibutes as the 3 to make it a flexible, stable shoe.
With the addition of InnerFlex™ as well as a 3mm reduction in stack height the midsole both flexible and responsive, and when paired with a widened platform and grooved outsole, provides excellent stability on uneven terrain.
Vibram® MegaGrip® rubber sculpted in the Altra TrailClaw™ pattern, continues to provide the traction needed for a variety of surfaces.
Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run.
Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents.
Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance.
"It's big, it's burly, it's run to run! One of the bigger surprises of the year, the Olympus 3.5 is one of the more fun to run trail shoes I’ve tested." Roadtrailrun.com, 2019
"Not only does it promote a more natural and controlled run while on the trail, buy buyers were also afforded substantial amounts of cushioning, incredible traction and very secure footwear." runnerclick.com, 2019
In terms of sizing, we find that all the Altra models run a bit small. Our best recommendation is to order at least a half size up from your conventional running shoes. For example, if you normally wear a US size 9 running shoe, you'll want to go with at least a US size 9.5 in Altra shoe
