The shoe is particularly comfortable with a very good and soft cushioning. Its soft cushioning, combined with its light weight, makes it particularly fast compared to "harder" shoes. In terms of grip, it is equivalent to the average (I have not yet tested it on wet terrain). Its only negative aspect, in my opinion, is that it is particularly sensitive, resulting in several damages (front and side) without having covered more than 60km with it. I believe it will not withstand for a long period of time, which automatically does not make it very suitable for a shoe that someone will use for both training and races. In conclusion, personally, I believe it is worth buying for someone who is looking for a fast, lightweight trail shoe with a soft cushioning.
Update: After two races (21 km) on hard terrain, the soles of the shoes have suffered damages and tears. I have used strong glue to fix them so they won't give up on me so quickly, and I now only use them for occasional training. It's a shame because my initial impression was very good.
