The Altra Paradigm 6 Shoe blurs the line between a road running shoe, everyday trainer, and support shoe. The Paradigm 6 is the first Altra shoe inspired by and developed by an Altra athlete—Kara Goucher, a two-time Olympian. Using Kara's input, Altra added the supportive Altra Ego Max midsole and slimmed down the overall design without sacrificing its maximalist fit and feel. Altra Ego Max midsole for extra bounce and durability, while remaining light and responsive InnerFlex midsole grooves improve flexibility and movement GuideRail provides support and encourages natural foot placement Innovarch arch support for a secure fit and customized feel Summer 2022 product Equipped With FootShape Toe Box Altra's FootShape toe box allows the toes to relax and spread out naturally, and the big toe to remain in a straight position for maximum stability and power. It is also designed to address biological differences in men’s and women’s feet. Balanced Cushioning Every Altra shoe is built on a Balanced Cushioning platform that positions the heel and forefoot an equal distance from the ground. This natural foundation aids in optimal alignment, cultivates better form, and encourages a low-impact landing.
