Winter can be an exhilarating time to trail-run. If you’re a runner undaunted by snowy singletrack, check Merrell’s new winter trail runner MTL Astrum, which comes complete with a snow-stopping and flexible high collar.
Put through its paces in the Merrell Test Lab, the MTL Astrum’s upper and insole radiates body heat back toward the foot and features snow tire–inspired Vibram lugs that grip on mixed winter terrain. Snow tires for your feet? We sure like the sound of that.Â
