The Alpinestars Stella SMX-1 R V2 Vented Boots are designed to offer women riders a combination of advanced protection, comfort, and ventilation for optimal performance on the bike. Featuring an anatomically engineered fit, these boots ensure a secure and supportive feel, with a rear flex zone equipped with a flex window that acts as an air intake for effective ventilation and airflow, keeping your feet cool during rides. The main upper is constructed from an advanced microfiber material that provides excellent abrasion resistance, durability, and a comfortable fit, making these boots suitable for both casual and competitive riding situations. The heel counter incorporates a soft Thermoplastic Rubber (TPR) insert that seamlessly works with the rear flex zone to enhance ankle freedom of movement while maintaining structural integrity and support. An innovative heel counter support system, combined with a strap closure featuring a TPR puller, offers a customizable fit and added support, ensuring stability during aggressive riding maneuvers. Extensive perforations throughout the upper enhance breathability, while the front bellow made from textile material further improves airflow, helping to prevent overheating. The ergonomic boot shaping offers a wide-ranging foot profile fit, delivering comfort and precision control, whether on or off the bike. The closure system includes a quick Velcro® strap for easy donning and adjustment, complemented by a replaceable bi-injected TPU forefoot slider with an easy-screw fixing concept for quick replacement. The sole features Alpinestars’ exclusive rubber compound with a grip pattern designed to improve feel, grip, water dispersion, and durability, providing confidence in various riding conditions. Integrated with the Transversal Protection Frame (TPF), the sole offers protection against transversal loads, enhancing safety. Flex zones at the instep and Achilles’ areas are constructed from lightweight microfiber, contributing to overall comfort, durability, and maneuverability. Thermowelded flex grooves control flexion and flexibility, while an internal toe box protection layer enhances durability and performance. The removable anatomic foot-bed, made with EVA foam and Lycra®, offers additional comfort and support. Internally, a moisture-wicking mesh lining maintains cooling comfort during extended rides. External protection features include a double-density ankle protector layered under the upper for abrasion resistance and shock absorption, a high modulus TPU heel counter, lateral ankle, and shift pad for impact protection, and a replaceable TPU forefoot slider for added safety. Overall, these boots are engineered to meet the rigorous demands of female riders seeking durability, protection, and ventilation in a stylish and functional package.
