Altra Women's Mount Blanc Speed

A high performance trail running shoe built for women who want to move fast on technical terrain without giving up the natural foot feel Altra is known for. The Mont Blanc Speed brings a dual-density midsole setup and Vibram's lightest outsole construction together in a package that prioritizes speed without sacrificing protection.

Highlights

• Dual-density EGO midsole with rim and core construction — Altra EGO MAX foam in the rim delivers cushioning and comfort while EGO PRO foam in the core adds responsiveness and energy return at the point of impact. Two different problems solved by two different foams in one midsole.
• Vibram Megagrip with Litebase outsole — Megagrip's proven traction on wet and dry surfaces paired with Litebase construction that reduces outsole weight without reducing grip coverage. Fast and confident on technical trail.
• Sandwiched TPU StoneGuard — Underfoot rock protection integrated between the midsole layers without adding meaningful stack height or weight. A critical detail for fast running on rocky, technical terrain where a sharp impact mid-stride can end a run.
• Zero drop platform at 29mm stack height — A natural foot position with serious cushioning underneath. High stack without the heel elevation that changes your gait and puts stress on your Achilles.
• Altra FootShape toe box — Room for natural toe splay through the forefoot with a secure, locked-in midfoot. Reduces hotspots and compression on long efforts where a narrow toe box becomes a real problem.
• Stitch-and-turn collar and tongue construction — A seamless, lightweight comfort detail at the ankle that eliminates the pressure points and irritation that standard collar construction creates on fast moving runs.
• 8.2 ounce weight — Light enough to move quickly without sacrificing the protection and cushioning needed for technical and all-day trail running efforts.

Best for

Women trail runners who want a fast, well-protected shoe for technical and all-day running efforts on demanding terrain. A strong choice for athletes who prefer a zero drop platform and wider toe box and don't want to compromise on speed or underfoot protection to get there.
