Our read

A capable ultra-distance racer for runners who want Altra's zero-drop platform with added propulsion from a full-length carbon plate; best suited to technical trail races rather than short, flat efforts.

Ride

29mm zero-drop stack combines Altra EGO MAX and EGO PRO foams for a bouncy, protective ride, while the Carbitex carbon plate adds propulsion without sacrificing the flex needed on technical trail.

Fit

Standard FootShape fit with a roomy toe box for natural toe splay and a secure midfoot lockdown, typical of Altra's neutral trail shoes.

Best for

Long and technical trail races, all-day trail running, and ultra-distance efforts where cushioning and propulsion matter over rugged terrain.

Avoid if

Runners who prefer a heel-toe drop, need max stability features, or are looking for a road racing shoe rather than a trail-specific carbon racer.
