Scarpa Alien Ultra Trail Running Shoe

Scarpa's most performance-focused trail runner, built for athletes who push into technical terrain at race pace and need a shoe that returns energy rather than absorbs it. The Alien Ultra combines a Pebax and carbon plate propulsion system with Vibram Megagrip traction and a precision-fit upper for a shoe designed to move fast on demanding ground.

Why We Carry It
When a serious trail runner walks in asking for the most technically advanced race shoe we carry, this is the answer.

Highlights

• Pebax and carbon plate midsole — A propulsion-focused plate system that stores and returns energy with each footstrike without the stiff, unnatural feel of some carbon plate shoes. Provides support and structure on technical terrain while allowing natural freedom of movement on variable ground.
• SC-ATPU midsole with 6mm drop — A 38mm heel and 32mm toe stack delivers serious cushioning on long efforts without raising the heel enough to compromise gait or agility on technical terrain.
• Vibram Megagrip outsole — One of the most trusted traction compounds available. Grips confidently on wet rock, mud, and mixed terrain across variable race conditions without compromise.
• TPEE Fabric and Eco Stretch Textile upper — Wraps the foot like a second skin for a precise, locked-in fit with minimal excess material. Lightweight and propulsive without sacrificing the foot security needed on technical descents.
• ULTRA last — A performance-specific last designed for the precise fit and forward momentum that serious trail running demands. Not a standard recreational fit.
• 295 gram half-pair weight — Competitive weight for a shoe with this level of carbon plate technology and outsole performance. Light enough to race in, capable enough to train in.
• Non-dyed microfiber lining — A clean, low-impact lining material that stays comfortable against the foot on long efforts without chemical treatments.

Best for

Competitive trail runners and mountain athletes who want a technically advanced race shoe with carbon plate propulsion and Vibram Megagrip traction for fast, precise movement on demanding terrain. A serious shoe for athletes who have outgrown standard trail runners and are ready for a performance-focused platform.
