"Fällt eher schmal aus. Gute Dämpfung und Stabilität. Sehr guter Trailrunning-Schuh."
— Susanne B. (5/5)
Comfortable cushioning yet light & great grip
"They were comfortable right out of the box. They grip to rocks like Velcro. The tongue is very well designed and snug to the feet. I have narrow feet and love them! Breathable. I don’t have any negative thoughts about them.
Great for running but I used them for long hikes."
