The Puma FOREVERUN NITRO heralds a new era of support and leadership. Combining RUNGUIDE SYSTEM features, this innovative model targets specific foot strike phases and takes support to a new level. This shoe is suitable for all runners, but has been specifically designed for those looking for the softness of a full NITRO midsole without compromising on stability. These features include a newly developed NITRO midsole that has 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 asymmetric heel cup keeps the foot in place and ensures a well-fitting shoe. The outsole design optimises overall pronation control, including a wider medial rubber segment that stabilises late pronation. The FOREVERUN NITRO is the latest leadership solution in Puma's performance running line designed for durability and comfort.
