Alpinestars Stella SMX-1R V2 Women's Motorcycle Boots - Black, US 11.5 / EU 44, Part Number 2224621-10-44

The Alpinestars Stella SMX-1R V2 boots are designed to provide women riders with an optimal fit, combining advanced materials and ergonomic features for enhanced comfort, protection, and performance. The main upper is constructed from a high-grade microfiber that offers excellent abrasion resistance, durability, and a comfortable feel during extended riding sessions. An anatomically engineered shape ensures a precise fit that accommodates a wide range of foot profiles for all-day comfort.

Key features include an innovative heel counter support system that works with a strap closure to improve fit and structural integrity, while a soft Thermoplastic Rubber (TPR) insert at the rear allows for greater ankle mobility and comfort over the bike's controls. The rear flex zone, combined with a flex window in the flex bellow, promotes better airflow and ventilation, helping to keep your feet cool and dry. The boots also feature a new ergonomic Thermoplastic Polyurethane (TPU) shift pad for increased durability in a critical area that experiences high stress during riding.

The closure system has been evolved for ease of use and security, with an anatomically angled strap that follows the natural shape of the rider’s instep, complemented by a quick-acting Velcro® closure with a TPR puller for convenience. Aramidic fiber wires ensure that the strap remains durable, thin, and lightweight. The outsole, made from exclusive Alpinestars compound rubber, offers excellent grip, water dispersion, and durability, with an integrated Transversal Protection Frame (TPF) to safeguard against transversal loads.

Additional protective features include reinforced zones such as the external heel counter, lateral ankle, and an integrated, replaceable TPU forefoot slider. The accordion flex zones at the instep and Achilles’ area are constructed from lightweight microfiber to improve maneuverability and comfort, both on and off the bike. The internal toe box layer enhances durability and feel, while the removable EVA and Lycra® foot-bed provides personalized comfort and support. An internal mesh lining promotes moisture-wicking and cooling, ensuring a comfortable riding experience regardless of conditions. The boots close with a reverse zip for easy entry and removal, making them a practical choice for everyday riding or competitive use.
