Altra Paradigm 4.5 - Men's


The most cushioned road running shoe in Altra’s lineup. The Altra Paradigm was originally inspired by tired feet at the end of the Badwater 135 ultramarathon. The updated version continues to offer ultimate protection from the pavement during your everyday runs. The unique take on a guidance system definitely makes this shoe stand out from the crowd, the system includes integrated StabiliPods™ for a stable platform and a GuideRail™ system for support just when you need it most. With an asymmetrical design and medial flaring lateral, this shoe offers increased for weak or tired feet, and is great for both neutral runners and those looking to upgrade from over structured "traditional stability" options.
