Hollow core technology reduces weight without sacrificing support

Take on legendary adventures in a shoe designed to keep up. We reengineered the upper for more durability, improved the midsole, and updated the outsole for more grip.

A revised midsole foam is lighter weight and designed to deliver a comfortable connection to the ground. No-sew overlays and a 100% recycled ripstop mesh upper are made for high-mileage durability while an improved outsole offers sticky underfoot grip.

Get that classic Altra feel with zero drop and our roomiest toe box, with plenty of room to help your toes move more freely, and space through the midfoot. Durability, grip, and connection on the trail? Legendary.

Best for trail running, hiking and thru hiking.
