Tackle winter trails fearlessly with the MTL Astrum. Built in the Merrell Test Lab where our most technical innovations are born, this winter trail runner with a snow-stopping collar radiates body heat back toward the foot and features snowtire-inspired Vibram® lugs that grip on mixed winter terrain. Because it’s never too cold for a trail run.


  • Snow Tire Traction: Inspired by snow tires, the MTL Astrum uses three densities of Vibram® rubber to bite into all types of winter trails (icy, snowy, slushy, muddy)

  • No-bulk Warmth: Barely-there heating technology reflects body heat back toward the foot, keeping toes warm without the use of heavy insulations & fleece

  • Resists the Elements: TPU Knit upper with M Select™ SHIELD technology wards off surface moisture, keeping feet dry
