The Altra Vanish Carbon 3 women’s shoes are competition footwear designed to combine lightness, responsiveness, and efficiency to enhance running performance.This model features a FAST RCE midsole made from a two-piece supercritical PEBA foam, Altra’s lightest and most reactive, engineered to deliver a fast and efficient stride. Its patented split carbon plate provides rigidity to increase speed while allowing the big toe to engage with greater power. The Racing FootShape™ last ensures a secure fit in the heel and midfoot at high speeds, while maintaining enough room for the toes to spread and generate more force. The upper is constructed from a seamless technical mesh that is breathable and lightweight, paired with a soft tongue to provide a distraction-free feel during the run.Weighing 220 grams and with a 4 mm drop, these shoes are designed to propel the runner forward thanks to a unique last shape combined with an improved rocker, offering a fresh and dynamic experience.
