Puma Eternity Nitro

The new Puma Eternity NITRO are part of its new line of running shoes designed for all distances and objectives. Thus, within this innovative bet of the German brand, these Eternity NITRO is the model that offers more support in each step, and is presented as a daily training shoe to move at more stable and calm rhythms.

As a running shoe for runners who require more support and stability, these Puma Eternity NITRO have an exclusive design in which Puma's latest generation technologies and cutting-edge materials are applied, such as the NITRO foam, the runGUIDE system or the PumaGRIP rubber compound, among others, and which of course do not go unnoticed in this model.

Puma Eternity NITRO, all its novelties and features

One of the main novelties of these Puma Eternity NITRO is located in the midsole, where they implement their cutting-edge technology with the NITRO foam. A foam that uses nitrogen gas in its avant-garde process, and makes the shoe go up a notch in areas of great weight such ascushioning, lightness and response. This translates into less strenuous running for the runner.

The midsole construction has a double layer of density, which is broken down into:

• In its bottom layer: Super Critical NITRO foam, which is what Puma calls it.

• In its upper layer with RunGUIDE: A firmer EVA layer that ensures both stability and grip.

The combination of these high-performance materials means that these Puma Eternity NITRO integrate a midsole with greater shock absorption, but also with a higher degree of energy return to keep moving forward.

On the other hand, as already mentioned, the stability component that comes with these Eternity NITRO from Puma is the runGUIDE system that offers support right where it is most needed, in the midfoot area, keeping the foot where it belongs. In addition, the Eternity NITRO includes a TPU piece in the heel to enhance the structure of the shoe, as well as a reflective element.

Upper and technical specifications of the Puma Eternity NITRO

On the upper, the Puma Eternity NITRO features a really aerodynamic and lightweight mesh. But what is really striking about this part of the shoe are the OptiFit straps on the medial and lateral part of the model to ensure an optimal and snug fit, which adapts better to the foot and offers more security. That feeling of comfort and support is also reinforced by its soft heel lining and padded tongue.

The outsole of the Eternity NITRO is configured with the exclusive PUMAGRIP rubber compound, highly resistant and capable of adapting to different surfaces with superior traction.

Regarding their technical specifications, Puma s Eternity NITRO have a drop of 8 millimeters, and weights of approximately 272 grams for the men's model, and 226 grams for the women's version. The concept of a shoe for moving at lively paces is evident, if the occasion calls for it; but it also offers the performance you need for running at lower, more relaxed paces.

By the way, there is a detail of these Puma Eternity NITRO that deserves a separate mention and that is that this running shoe for women has a specific last, which guarantees a better adaptation to the female foot, since it has a more sculpted arch design, as well as a narrower heel area. A technological resource that provides a higher level of comfort in each kilometer run.

With all that has been said about these Puma Eternity NITRO, at RUNNEA it is clear to us that this model is here to stay, and also to compete, toe-to-toe, with real heavyweights for running on asphalt like the Nike Vomero 15 or the Brooks Glycerin 19 GTS, among other models.

To recap, some of the details to keep in mind about these Puma Eternity NITRO are summarized in the following points:

• Engineered mesh in the upper that offers more support.
