Very good shoe, lightweight for training and feels even lighter on the foot, the nitro foam is soft and efficient, and it is very comfortable on the inside. The outsole is on another level compared to the competition. I have used it from easy to competitive 5k. At its original price, it is considered decent, but at a price below 100€, it is one of the best value for money. Pay attention to the size, consult Puma's sizing and get (at least) one size smaller. Currently, they have about 220km and they are like new.

On my own feet they didn't fit (wide foot with high arch).
In case you decide to buy them, prefer a larger size.
They are very soft, but they fit better on narrow feet.
Their advantage is the amazing nitro sole that absorbs shocks perfectly.
Also, the sole is fully slip-resistant with very good rebound.
Overall, they will not disappoint anyone in running.

First impression excellent. Ideal for running, very comfortable, very good fit on the foot, very good shock absorption. The durability over time remains to be seen.
