The ForeverRUN NITRO™ dawns a new era of support and guidance for all runners, providing the softness of a full NITROFOAM™ midsole without compromising stability. It features the newly developed NITROFOAM™ midsole with two different densities – a softer core with a firmer rim – and an asymmetrical heel counter to hold the foot in place through every stride. The theme also continues on the outsole, with a wider medial rubber segment that stabilises late-stage pronation. In short, it's the perfect blend of support and cushion.<ul><li>NITRO™: Advanced nitrogen-infused&nbsp;foam designed to provide superior responsiveness and cushioning in a lightweight package</li><li>PWRTAPE: Targeted upper reinforcement for support and durability</li><li>RUNGUIDE: Firm density guide rail designed to keep your foot aligned and centred through each stride</li><li>PUMAGRIP: Durable performance rubber compound designed for all-surface traction</li></ul><ul><li>Engineered mesh upper</li><li>Moulded heel technology</li><li>Flared rubber outsole</li><li>Cushioning level: Max</li><li>Heel-to-toe drop: 0mm</li><li>Shoe pronation: Overpronation</li></ul>
