The Altra Mont Blanc Speed is Altra's lightweight trail weapon, built for runners who want to fly uphill and bomb descents without sacrificing protection or natural foot function. A dual-density midsole pairs bouncy EGO PRO foam in the core with durable EGO MAX in the rim for a snappy, responsive ride at 29mm of zero-drop cushion, while a Vibram Megagrip Litebase outsole keeps weight down and traction dialed on wet rock, loose dirt, and everything in between. Finished with a secure Standard FootShape fit, a sandwiched TPU StoneGuard for rocky terrain, and a gusseted tongue to keep trail debris out, this is the go-fast shoe that makes every run feel like race day.
