Alpinestars Stella SMX-6 V3 boots

Anatomically designed for an optimized female fit and equipped with a host of innovative safety and protection features, the Stella SMX-6 v3 is the ultimate all-rounder for track and performance riding, incorporating race-derived technology and materials to give riders a decisive performance advantage on the track and road. A women's-specific fit ensures optimal comfort. Advanced microfiber upper construction provides lightweight, high-performance abrasion protection and excellent flexibility. New front and rear flexion zones utilize textile with over-injected soft TPU to improve impact abrasion while promoting natural forward and backward movement. An evolution of Alpinestars' unique ankle protection system provides biomechanical support and protection between the lateral upper calf, shin, and ankle for greater ankle mobility while limiting hypertorsion, hyperextension, and hyperflexion, as well as protecting the Achilles tendon and ankle. Alpinestars' Lace-Look system is constructed from an advanced polymer resin for guaranteed fast, precise, and secure closure. It features a new TPU shifter zone for excellent protection on the lower medial side. A new, strategically positioned, race-derived TPU shin guard offers superior impact and abrasion resistance. Dual-density TPU ankle protectors are strategically positioned between the upper and padded lining to provide strategic protection in key areas. A replaceable, screw-mounted, dual-density TPU toe slider provides comprehensive protection around the outer toe area while remaining highly flexible for walking comfort. The replaceable heel slider and outer lateral heel slider are strategically positioned to ensure optimal shock dissipation and absorption, while promoting gliding in the event of an accident. The Stella SMX-6 v3 boot is CE-certified to EN 13634:2017.
