A premium trail racer combining a full-length carbon plate with Altra's signature zero-drop platform and high cushion, aimed at runners tackling technical, long-distance trail races who already trust zero-drop mechanics.
High-stack EGO MAX/PRO hybrid midsole paired with a full-length carbon plate delivers a propulsive, protective ride at zero drop, prioritizing efficient forward motion over ground feel.
Standard FootShape fit offers Altra's typical roomy toe box with a secure midfoot via ghillie lacing and a plush molded heel collar; not a narrow-fit shoe.
Trail racing, technical terrain, and all-day/ultra-distance trail efforts for runners accustomed to zero-drop shoes.
Avoid if you need a non-zero-drop platform, are new to Altra's zero-drop mechanics, or want a lightweight minimalist shoe rather than a max-cushion racer.
