In theperiodic table of elements 7 is the atomic number associated with nitrogen, whose symbol is N (from the Latin nitrogenum).
And it is precisely nitrogen, in the form of foam, that distinguishes the shoes from the German brand’s running collection: an advanced technology, NITRO FOAM precisely, that combines responsiveness while ensuring exceptional cushioning. All this in an extremely lightweight shoe: 299 grams for the men’s version and only 244g. For the female one.

It is from this concept that PUMA and STRAVA have created a new challenge for all European runners, a challenge where 7 is a recurring element. The challenge, which starts on Saturday, Nov. 13, is divided into two installments, depending on your level of preparation: the first, from Nov. 13 to Nov. 20, consists of running 7k in one week-they can either be your first goal or your fastest miles!
In the second phase, from Nov. 20, the goal becomes more ambitious: to run, in the time of two weeks, a half marathon: 21 km spun or three sessions of 7k each.
At the end of the challenge, in addition to the virtual badge, you will be directed to PUMA’s website where you will be entered into a drawing for a compelto of PUMA apparel and a pair of MAGNIFY NITROs.
