Alpinestars Stella SMX-1 R V2 Vented Motorcycle Boots - Women’s Black US 11.5 / EU 44

The Alpinestars Stella SMX-1 R V2 Vented Boots are designed specifically for women, offering an optimized fit through anatomical engineering and advanced materials. Featuring a rear flex bellows with a flex window, these boots provide effective ventilation and airflow, ensuring comfort during long rides or intense sessions. The main upper is crafted from durable microfiber, offering excellent abrasion resistance and a comfortable fit that adapts seamlessly to your foot's profile. The boots incorporate a thermoplastic polyurethane (TPU) shift pad for enhanced durability in critical areas, providing reliable protection and longevity.

The heel counter is reinforced with a soft TPR insert that works in conjunction with the rear flex zone to improve ankle mobility and overall comfort on the bike's controls. An innovative heel counter support system coupled with a strap closure enhances fit, support, and structural integrity, while extensive perforations promote maximum airflow. The front bellow, made from breathable textile material, further improves ventilation, helping to keep your feet cool and dry. The ergonomic boot shape ensures a streamlined fit across a wide range of foot profiles, and the strap features a TPR puller for easy adjustment.

For added durability and lightweight performance, the strap closure system uses aramidic fiber wires, and the closure is anatomically angled to follow the natural shape of the rider’s instep. The sole is constructed from Alpinestars' exclusive rubber compound with a grip pattern designed for superior feel, grip, water dispersion, and durability. The quick-release Velcro® closure system secures the boots firmly over the instep, allowing for quick in and out while maintaining flexibility. The sole also integrates the Transversal Protection Frame (TPF) for protection against transversal loads. Additional features include lightweight microfiber construction for the instep and Achilles flex zones, thermowelded flex grooves to control flexibility, and an integrated replaceable TPU forefoot slider with an easy-screw fixing system. A reverse zip closure enhances convenience, and layered ankle and toe box protectors deliver abrasion resistance and shock absorption. The removable anatomic foot-bed, lined with EVA foam and Lycra®, provides optimal comfort and support, while internal mesh lining ensures moisture-wicking and cooling during rides.
