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, thanks to a wider medial rubber segment stabilising late-stage pronation. In short, it's the perfect blend of support and cushion.
