It’s no easy tusk – sorry, task – running on rocky terrain. This shoe from Mammut feels as though it’s been designed with mountain environments in mind; the wide sole base provides excellent stability and the toe area is protected by a panel and hefty toe bumper. The Sonar treads have a radial pattern, spreading outwards from the midfoot, which provides great multi-directional grip. Traction is limited in mud as the lugs aren’t the longest, but it excels on rocky trails. It’s a comfy shoe to run in, with 9mm drop – just the right level of cushioning and trail-feel. The lacing system could feel more secure, though, and the Gore-Tex lining traps the sweat on warmer days.
Comfortable work horse of a shoe; ideal for cold, damp days and rocky trails.
