Originally Inspired by tired feet at the end of Badwater 135, the Paradigm continues to innovate with the updated 4. This max cushion shoe features the performance of the Altra EGO midsole and the comfort of a knit upper. This shoe stands out from the crowd with its unique take on guidance with integrated StabiliPods for a stable platform and a GuideRail system for guiding support when you need it, but not when you don’t. The asymmetrical design with medial flaring increases lateral support for weak or tired feet and is great for both neutral runners and those looking to upgrade from over structured “traditional stability” options.
