The New Balance Fresh Foam Hierro v4 has landed in the market with many changes compared to what we have seen so far in this reference saga for mountain running of the American brand. This fourth version of the Hierro v4 comes more complete and with a completely renewed upper.
Thus, the idea behind these new New Balance Fresh Foam Hierro v4 is to run more comfortably for more kilometers, while maintaining cushioning, fit and traction. All this translates into a very versatile trail running shoe, suitable for neutral runners, although they are also able to offer enough stability for runners with mild pronation.
As in the New Balance Fresh Foam Hierro v3, the star material of the New Balance Hierro v4 is still the exclusive Fresh Foam foam, but this time more evolved with the application of laser engraving, which allows to create controlled geometries from D2D. A technological resource that reinforces the cushioning performance of Fresh Foam, and whose purpose is to be able to absorb, to a greater extent, the impacts, regardless of the number of kilometers that are run.
In this way, this new way of developing and positioning the Fresh Foam foam makes the New Balance FF Hierro v4 have a highly cushioned midsole, which is not exempt from flexibility, while at the same time it favors a significant reduction in weight. All this results in a better response in each stride.
As we have previously mentioned, these Fresh Foam Hierro v4 also include a renewed upper, whose most outstanding note is the incorporation of an elastic film to offer a more suitable fit, and that adapts to any distance to be run. Here, in the upper of this all-terrain trail running shoe, the bootie-shaped design also has a lot to say, since it makes the fit of the model even more precise, as well as increasing safety.
The external heel counter, as well as the adjustment strap, establish a successful synergy between the midsole and outsole.
Another thing that is maintained in these New Balance Fresh Foam Hierro v4 is the Vibram MegaGrip outsole, through which exceptional grip and durable traction is guaranteed, practically, on any terrain on which you face your next trail adventure.
In short, we can say that the New Balance Hierro v4 is a model for everyone, as long as they are looking for the option of wearing a rolling trail shoe, comfortable, not excessively slow, and with optimal grip, focused for all types of runners, from the lightest to the heaviest.
