Training is an important part of any kind of mountaineering activity, and that consists of various options, such as running, and specifically trail running. Although I do not particularly like to run on mountain trails -I much more prefer to enjoy the views and the surrounding environment- I understand the importance of this type of exercise. For this type of activity I use the Salomon Speedcross 3 purchased from Ali Express. Some say these shoes are genuine but with some minor defects, instead others claim are rip-off Salomon models. Either case, this will be a review for the specific shoes.
