Alpinestars Stella SMX-1 R V2 Vented Boots - Black, US 6 / EU 37 (Part Number 2224121-10-37)

The Alpinestars Stella SMX-1 R V2 Vented Boots are designed to deliver superior comfort, protection, and performance for female riders. Featuring an anatomically engineered fit, these boots incorporate a rear flex zone with a flex window that functions as an air intake, providing effective ventilation and airflow to keep your feet cool during rides. The main upper is constructed from an advanced microfiber material that offers excellent durability, abrasion resistance, and a comfortable fit, ensuring longevity and reliability in demanding riding conditions.
The heel counter is reinforced with a soft Thermoplastic Rubber (TPR) insert, working seamlessly with the rear flex zone to enhance ankle mobility and overall comfort. The innovative heel support system, combined with a strap closure, provides a secure fit while maintaining structural integrity, accommodating a wide range of foot profiles. Extensive perforations throughout the upper allow maximum airflow, complemented by a textile front bellow for added breathability.
Ergonomically shaped for a streamlined fit, the boot features an adjustable strap with a TPR puller for easy handling and a durable, lightweight aramidic fiber wire system that ensures the strap closure remains secure. The closure system is further optimized with an anatomically angled strap that follows the natural shape of the rider’s instep. The sole is crafted from Alpinestars' exclusive rubber compound with a grip pattern designed to improve feel, grip, and durability, while also providing water dispersion. A quick and secure fit is achieved with the front Velcro® closure system, which permits excellent flexibility and adjustment.
Integrated with the Transversal Protection Frame (TPF), the sole offers added protection against transversal loads, enhancing safety. The instep and Achilles' flex zones are made from lightweight microfiber, promoting durability, comfort, and maneuverability on and off the bike. Thermowelded flex grooves allow precise control over the boot's flexion and flexibility, while an integrated, replaceable bi-injected TPU forefoot slider features an innovative screw fixing for quick replacements. The reverse zip closure ensures easy in and out, and a double density ankle protector layered beneath the upper offers abrasion resistance and impact protection. External high modulus TPU components, including the heel counter, lateral ankle, and shift pad, further improve shock absorption and durability.
Inside, the removable anatomic foot-bed with EVA foam and Lycra® provides added comfort and support, while the internal mesh lining wicks moisture for a cooling, comfortable ride. Overall, the Alpinestars Stella SMX-1 R V2 Vented Boots combine advanced materials, thoughtful ergonomic design, and protective features to meet the needs of female motorcyclists seeking performance and comfort in a versatile riding boot.
