Originally inspired by tired feet at the end of the Badwater 135, the Altra Paradigm continues to innovate with the updated 4.5. This max-cushion shoe features the performance of the Altra EGO™ midsole and the comfort of a knit upper. 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. Stack Height: 30mm. Insole: 5mm. Weight: 11.2oz.
