The Foreverrun Nitro dawns a new era of support and guidance for all runners, providing the softness of a full Nitro midsole without compromising stability. It features a newly developed Nitro 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, thanks to a wider medial rubber segment stabilizing late-stage pronation. In short, it's the perfect blend of support and cushion.
