Alpinestars Stella SMX-1 R V2 Vented Boots - Black US 11 / EU 43 (Part Number 2224121-10-43)

The Alpinestars Stella SMX-1 R V2 Vented Boots are designed to deliver optimal performance, comfort, and protection for female riders. Crafted with an anatomically engineered fit, these boots feature a rear flex zone equipped with a flex window that functions as an air intake to enhance ventilation and airflow, keeping your feet cool during rides. The advanced microfiber uppers provide durability, abrasion resistance, and a comfortable fit, ensuring longevity and reliable performance under demanding conditions.
Built for enhanced support and mobility, the boots incorporate a soft Thermoplastic Rubber (TPR) insert at the heel counter that works seamlessly with the rear flex zone to improve ankle movement and comfort on the bike's controls. The innovative heel counter support system, combined with a strap closure that includes a TPR puller, offers a secure fit and structural integrity. Extensive perforations throughout the upper maximize airflow, while a textile front bellow adds breathability, making these boots suitable for warm weather riding. The ergonomic boot shape is designed for a wide-ranging foot profile, providing both comfort and a precise fit for various foot shapes.
Featuring a durable rubber sole with an exclusive Alpinestars grip pattern, these boots promote excellent feel, grip, water dispersion, and durability. The front Velcro® closure system allows for quick and secure fastening over the instep, granting flexibility and ease of use. The sole includes Alpinestars' Transversal Protection Frame (TPF) for additional security against transversal loads. Integrated flex zones made from lightweight microfiber in the instep and Achilles area enhance maneuverability and comfort both on and off the bike. Thermowelded flex grooves control flexion, while a removable, anatomically shaped foot-bed with EVA foam and Lycra® provides added support and comfort.
Protection features include double-density ankle protectors layered under the upper, an external high-modulus TPU heel counter, and layered internal toe box protection for durability and performance. The external bi-injected TPU forefoot slider features an easy-screw fixing system for quick replacements. The reverse zip closure allows for easy in-and-out access, and extensive internal mesh lining ensures moisture-wicking and cooling comfort. These boots are built with an emphasis on protection, ventilation, and rider comfort, making them ideal for performance-oriented female motorcyclists.
