Altra made it faster. The Vanish Carbon 2 features a full-length carbon fiber plate, even more lightweight midsole foam for a soft feel, and improved flexibility. It’s ready to rocket you through a tough speed workout and obliterate PRs on race day. Negative splits? Oh, positively. We built it to perform by increasing the stack height from 33mm to 36mm, with Altra EGO PRO™ midsole foam that’s 32% lighter in weight. This updated foam is more pliable, for added cushion and response. An updated full-length carbon fiber plate delivers a 14% increase in asymmetry, allowing for a more natural (and probably faster) stride. This redesign overhaul combined with additional flex grooves in the outsole gives you 75% improved flexibility. With Altra’s signature FootShape fit, you get a roomy toe box with space for your toes to move freely, snug midfoot, and zero drop, so you can move the way you were designed to. Toe the starting line with confidence and swag in this techy race-day ready shoe.
