The best training shoe, I've ever had. Versatile, light and super comfortable both on long slow runs and also on some speedy intervals. Very durable and performing absolutely amazing also after very long milage, not only on trails. Have done a 28w marathon preparation in these as the main training shoe and it gone also far beyond. After 1200km started to notice some wear in the cushioning, but overall condition very good, not suitable for running anymore, but I am sure that I will do another 500km or so for daily walking and hiking activities.
