Alpinestars Stella SMX-1 R V2 Vented Boots - Black, US 5 / EU 36 (Part Number: 2224121-10-36)

Designed specifically for female riders, the Alpinestars Stella SMX-1 R V2 Vented Boots offer a combination of comfort, protection, and performance. The anatomically engineered fit ensures optimal support and responsiveness, with a rear flex zone featuring a flex window that acts as an air intake for effective ventilation and airflow, keeping your feet cool during rides. The advanced microfiber upper provides durability, abrasion resistance, and a comfortable fit that adapts to your foot's shape, making long rides more enjoyable.
The heel counter incorporates a soft Thermoplastic Rubber (TPR) insert that works seamlessly with the rear flex zone, offering enhanced ankle mobility and control. An innovative heel support system, combined with a strap closure featuring TPR pullers, improves fit, support, and structural integrity while maintaining ease of use. Extensive perforations throughout the boot maximize airflow to prevent overheating, and a textile front bellow enhances breathability, making these boots suitable for warmer conditions.
The ergonomic design includes a forefoot streamlining shape that accommodates a wide range of foot profiles for maximum comfort and control. The evolved strap closure system, with aramidic fiber wires, ensures durability, lightweight performance, and a secure fit. The strap is anatomically angled to follow the natural shape of the rider’s instep, providing additional support. The sole features Alpinestars’ exclusive rubber compound with a grip pattern that enhances traction, feel, and durability, along with water dispersion capabilities.
For protection and flexibility, the boots include integrated flex zones at the instep and Achilles area, constructed from lightweight microfiber. Thermowelded flex grooves allow for controlled flexion and flexibility, while a replaceable bi-injected TPU forefoot slider with an easy-screw fixing system simplifies maintenance. The external high-modulus TPU heel counter, lateral ankle, and shift pad offer shock absorption and durability, ensuring safety during aggressive riding.
The internal toe box protection layered under the upper adds durability and improves the overall feel. A removable anatomical footbed with EVA foam and Lycra® delivers additional comfort and support, complemented by an internal mesh lining that provides moisture-wicking and cooling comfort. The quick-in and out reverse zip closure, combined with a Velcro® strap for a secure fit, makes these boots both user-friendly and performance-ready, suitable for riders seeking a high-performance, ventilated motorcycle boot with excellent protection features.
