MAMMUT DOUBLES DOWN ON TRAIL RUNNING WITH AENERGY FOOTWEAR
Seon, Switzerland | Trail running is a mountain sport. It demands speed and precision, but also protection, grip and confidence when the terrain turns technical. For Spring/Summer 2026, Mammut reinforces its commitment to moving fast in the mountains – with expanded support for the global trail running community and the newest highlights from the Aenergy footwear line.
