The Puma FOREVERUN NITRO heralds a new era of support and leadership. Combining RUNGUIDE SYSTEM features, this innovative model targets specific footprint phases and takes support to a new level. This shoe is suitable for all runners, but is specifically designed for those seeking the softness of a full NITRO midsole without compromising stability. These features include a newly developed NITRO midsole that features two different densities - a first in the industry. The FOREVERUN NITRO is softer on the inside and has a firmer edge, so it runs particularly smoothly thanks to the new geometry. The mesh upper combined with an asymmetrical heel counter keeps the foot in place and provides a well-fitting shoe. The outsole design optimizes overall pronation control, including a wider medial rubber segment that stabilizes late pronation. The FOREVERUN NITRO is the latest leadership solution in Puma's performance running line, designed for durability and comfort.
