Alpinestars Stella SMX-1 R V2 Vented Boots - Black US 8.5 / EU 40 (Part #2224121-10-40)

Designed specifically for female riders, the Alpinestars Stella SMX-1 R V2 Vented Boots provide an optimal fit with anatomically engineered shaping that enhances comfort and performance. The rear flex zone features a flex window that functions as an air intake, promoting effective ventilation and airflow to keep feet cool during demanding rides. Constructed with an advanced microfiber upper, these boots offer superior durability, abrasion resistance, and a lightweight feel, ensuring long-lasting performance in various riding conditions. The heel counter incorporates a soft thermoplastic rubber (TPR) insert, working seamlessly with the rear flex zone to improve ankle mobility and comfort while maintaining structural integrity for aggressive riding scenarios. An innovative heel counter support system paired with a strap closure enhances fit, support, and overall stability, making these boots ideal for both casual and competitive riders. Extensive perforations throughout the boot maximize airflow, complemented by a front bellow made from breathable textile material for added ventilation. The ergonomic shape of the boot offers a streamlined forefoot profile, accommodating a wide range of foot shapes for maximum comfort during prolonged use. The strap features a TPR puller for easy adjustments, while aramidic fiber wires ensure a durable, lightweight closure system that maintains a secure fit. The anatomically angled closure strap follows the natural shape of the rider’s instep, providing precise support. The exclusive Alpinestars rubber sole with grip patterning ensures excellent traction, water dispersion, and durability, suitable for various terrains. A quick-release Velcro® system over the instep allows for secure and swift entry and removal, along with high flexibility. The sole integrates Alpinestars' Transversal Protection Frame (TPF), offering additional protection against transversal loads. Lightweight microfiber is used in the instep and Achilles’ flex zones to enhance durability and maneuverability both on and off the bike. Thermowelded flex grooves control the shoe’s flexion, while a replaceable bi-injected TPU forefoot slider with an easy-screw fixing system simplifies maintenance. The reverse zip closure provides convenient in and out, and a double density ankle protector layered under the upper enhances abrasion resistance and shock absorption. External high modulus TPU heel counters, lateral ankle, and shift pads improve impact protection, while internal toe box protection adds durability and performance. The removable anatomical foot-bed, featuring EVA foam and Lycra®, offers comfort and support, complemented by an internal mesh lining that wicks moisture and maintains cooling comfort for extended rides. Overall, the Alpinestars Stella SMX-1 R V2 Vented Boots combine innovative design, protective features, and superior ventilation to meet the demanding needs of female motorcyclists seeking performance, comfort, and durability.
