The ForeverRun NITRO embarks on a modern era of support and guidance for all runners, integrating the cushioned comfort of a full NITRO midsole without sacrificing stability. It is equipped with a novel NITRO midsole constructed from two different densities – a softer core framed by a firmer perimeter – and an asymmetrical heel counter for adequate foot containment throughout the gait cycle. The concept extends to the outsole, equipped with an enlarged medial rubber area for pronation control. In short, a perfect fusion of support and cushioning is achieved. Key Technologies: NITRO: Advanced nitrogen-injected foam designed to provide superior responsiveness and cushioning in a lightweight package. PWRTAPE: Targeted upper reinforcement for support and durability. RUNGUIDE: Firm density guide rail designed to keep the foot aligned.
