Women's Altra Vanish Carbon 3

Race Day Speed with a Natural Edge Built for the grind of race day, it’s light, responsive, and brutally efficient. The Vanish Carbon 3 is Altra speed – reimagined. An all-new FAST RCE midsole is a supercritical, two-piece full PEBA foam that’s our lightest and most responsive, made for a fast and efficient ride. A patent-pending split-toe carbon fiber plate provides the rigidity to fuel speed while allowing the big toe to engage in a more powerful way. Our unique last shape combined with an enhanced rocker and 4mm drop propels runners forward with each step for a fun and fresh experience. Altra’s Racing FootShape™ provides a secure heel and midfoot at high speeds but maintains room in the toe box so your toes can splay and engage for more power. A race-day upper is designed for a seamless, breathable engineered mesh with a soft, lightweight tongue for a zero-distraction feel. An innovative eyestay design ensures proper midfoot lockdown while keeping the toes free to splay. In lab testing, the Vanish Carbon 3 improved running economy by 2.6% compared with the Vanish Carbon 2, rivaling current super shoes in the market. So you can keep crushing through the whole 26.2, without crushing your toes. Key Features Supercritical, Two-Piece Full PEBA Foam: our lightest and most responsive foam for a fast, efficient ride.
