ForeverRun Nitro 2

The ride is steady, planted and unhurried. This is a shoe that rewards a consistent easy-to-steady rhythm rather than surges. The dual-density Nitrofoam gives you a cushioned but controlled landing, with enough firmness underneath to stop you sinking and wallowing over the miles. The 10mm drop and deep heel make heel-to-toe transitions smooth for rearfoot strikers, though the shoe does not have much natural pop or rebound, so do not expect it to spring you forward. At 295g the weight is honest and noticeable, and that mass is the trade-off for the stability and protection you get. Hold your easy pace and it feels composed and dependable. Try to run fast in it and it feels like the wrong tool. We would keep it for the runs where staying comfortable and controlled matters more than speed.

There is plenty of cushioning here, and it is the protective, long-haul kind rather than the soft-and-bouncy kind. The 38mm heel stack means your legs are well insulated from the road on long runs, and the dual-density Nitrofoam setup keeps the ride from ever feeling harsh or dead. What you will not get is that pillowy, sink-in softness of a pure max-cushion trainer. Puma has tuned this foam firmer on purpose, because a stability shoe that collapses under you is not stable. The result is cushioning that stays consistent from the first mile to the last, holding its shape when your form starts to fade. For heavier runners or anyone who values a supportive, non-mushy platform on long efforts, that firmer balance is a real strength rather than a compromise.

Stability is the whole point of this shoe, and it takes the modern guided approach rather than the old-school corrective one. Instead of a hard medial post jammed under your arch, the ForeverRun Nitro 2 relies on a wide, structured base, Puma's RunGuide sidewalls that cradle the foot, and a firmer foam density to keep everything planted. The effect is a shoe that gently discourages your foot from rolling inwards without ever feeling like it is fighting your natural motion. It suits mild to moderate overpronators and neutral runners who simply want a more locked-down, secure feel underfoot on long runs. If you have severe overpronation and have been prescribed a strong motion-control shoe, this softer style of support may not be firm enough for you, and a more aggressively posted trainer will serve you better.

The upper is built for security and long-run comfort rather than minimal weight. It uses a supportive engineered mesh that holds its shape, paired with a padded, structured heel counter and a well-cushioned tongue and collar that lock the foot without hotspots. That padding adds a little weight but pays off on longer efforts, where a flimsy upper tends to let the foot shift. Breathability is fair rather than outstanding, so in peak summer heat your feet will run a touch warm compared with a thin racing mesh, but for typical UK conditions it is comfortable and dependable. Overall the fit is plush and reassuring, the kind of upper you stop noticing because it just holds you where it should.
