The Puma Foreverun Nitro dawns a new era of support and guidance. Targeting specific foot strikes stages through a combination of the Runguide System features this innovative model takes support to a new level. This shoe performs for all runners but is specifically designed for those looking for the softness of a full Nitro midsole without compromising stability. This shoe features a newly developed Nitro midsole that has two different densities – an industry first. Softer on the inside with a firmer rim the Foreverun Nitro rides super smoothly with new geometry. An engineered mesh upper combines with an asymmetrical heel counter to hold the foot in place in a well-fitting shoe. The outsole design optimizes overall pronation control including a wider medial rubber segment stabilizes late-stage pronation. The Foreverun Nitro is the newest guidance solution in Puma’s performance running line built for durability and comfort.
