Alpinestars Stella Smx-1 R V2 Vented Boots Black 10

The Alpinestars Stella SMX-1 R v2 Vented is a low-cut women’s sport riding boot, designed for riders who want race-inspired performance with all-day comfort. Compact and sleek, it fits easily under technical riding pants and is ideal for sport and sport-touring use where freedom of movement and walkability are just as important as protection.

The upper is constructed from lightweight, abrasion-resistant microfiber with extensive perforation zones and a textile front flex panel to maximize airflow. This highly ventilated design keeps your feet cooler during warm-weather rides and spirited sessions on the road or track. An anatomically engineered women’s fit ensures the boot wraps closely around the foot and ankle for enhanced comfort and precision.

At the rear, an innovative heel contour support system works together with the closure strap to provide a secure, supportive fit and structural integrity. A soft TPR insert at the back of the heel integrates seamlessly with the rear flex zone, allowing greater ankle mobility and comfort on the bike’s controls. Accordion flex zones at the instep and Achilles area deliver smooth, controlled movement for shifting, braking, and walking.

In terms of protection, the Stella SMX-1 R v2 Vented is equipped with dual-density ankle protectors on both sides, an external high-modulus TPU heel counter, and an internal toe reinforcement layered beneath the upper. A new ergonomic TPU shift pad increases durability in a high-wear area, while the integrated, replaceable bi-injected TPU toe slider can be quickly swapped out using a simple screw mounting system.

The specially developed rubber outsole features Alpinestars’ TPF (Transversal Protection Frame) to help guard against transverse loads while maintaining flexibility and feedback. Its grip pattern is designed for excellent traction on the footpegs and stable footing off the bike, with thermo-welded flex grooves that manage how the sole bends for predictable, controlled flex.

Inside, a breathable mesh lining and removable anatomical EVA footbed with Lycra top provide cushioning, ventilation, and moisture management for long days in the saddle. The combination of a reversed side zipper and an ergonomically oriented Velcro closure across the instep allows quick entry and a secure, finely tuned fit.

CE-certified to EN 13634:2017, the Alpinestars Stella SMX-1 R v2 Vented boot delivers a refined blend of ventilation, agility, and protection in a compact women’s sport boot tailored for performance on and off the bike.
