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 a 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 Features: 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.
