Puma Eternity NITRO: a stable, cushioned daily trainer

Puma broke back into the competitive running scene in 2021 with an innovative NITRO lineup. It includes five models that range from daily trainers to elite-level race shoes.

Puma Eternity Nitro cushioning

The Eternity takes up the niche of easy, daily runs with a touch of stability for overpronation. It can be described as a stable version of Puma Velocity NITRO.

Helps with mild to moderate overpronation

Acting similarly to Brooks GuideRails, Puma's RUNGUIDE creates bumpers on the sides to help the foot roll straight through the gait cycle. Unlike stability shoes of old, it offers more subtle support that can even be used by neutral runners on their recovery days.

Bouncy cushioning

Underneath the firmer RUNGUIDE is a softer layer of nitrogen-infused Super Critical foam. Built with similar properties as Skechers Hyperburst, it shows higher levels of energy return than standard EVA.

Enhanced lockdown

With OptFit straps stretching from the midsole to the top on both sides, you get even stronger lateral support when the laces are tightened.

Adapted to women's feet

The women's version is designed with a lower instep, narrower heel, and other small details that create a more tailored fit.
