Alien Ultra Limited Edition

High-performance technical fabric upper (80% TPEE, 20% PA) with a knit structure, designed to balance mechanical resistance (abrasion and tearing) with lightness. The PA component ensures a non-stretch structure in a controlled direction, promoting effective foot containment and stability during changes of direction. High breathability and quick-drying properties complete the material’s technical profile.

“Sock-Fit Plus” construction with integrated gaiter: combines a structured and durable zone (upper + lacing system) with a snug, adaptable section above the ankle, featuring an anti-debris sock for continuous protection. The structure minimizes pressure points (flat laces with double eyelets) and ensures sensitivity and precision thanks to its thin construction, with no intermediate layers between the foot and the strobel (no sockliner, allowing direct contact with the midsole wedge). The engineering of lateral containment in the lower foot area is entrusted to a heat-welded, non-stretch fabric, ensuring stability and control during dynamic phases.

Flat laces reduce pressure points and, thanks to their shaped profile, increase grip and lacing stability, ensuring a secure knot. Made from 100% recycled polyester, they combine performance and sustainability.

The upper integrates a minimal, non-dyed black microfiber lining, reduced to the essentials to ensure lightness, grip, and durability where needed. Concentrated on the heel and underfoot area, it provides comfort, protection, and breathability for a performance-oriented feel.

The sandwich wedge in 100% Super Critical Foam A-TPU combines lightness, elastic rebound, and long-term durability. Its continuous geometry from heel to toe guides each step forward, optimizing stability and smoothness without unnecessary weight. The “Squid Plate” insert, made of Pebax nylon with 30% carbon fiber, reduces weight while enhancing stability and elasticity through planar geometries and modulable concavities that even out mechanical resistance. Together with the wedge, it forms a balanced system to guide the shoe’s ride/flow. The Vibram Megagrip outsole delivers optimal grip and smoothness. Its 3 mm lugs are designed to maximize traction and durability, with each pin positioned according to force and wear patterns, without any superfluous elements.
