Alpinestars Stella SMX-1R V2 Motorcycle Boots – Black, US 10 / EU 42 (Part Number 2224621-10-42)

The Alpinestars Stella SMX-1R V2 boots are designed for women seeking high-performance motorcycle footwear with an optimized fit. Crafted with an advanced microfiber upper, these boots offer excellent abrasion resistance, durability, and comfort for demanding riding conditions. The anatomically engineered shape ensures a secure and ergonomic fit that adapts to the female rider’s foot profile, enhancing control and reducing fatigue during extended rides. The innovative heel counter support system, combined with a strap closure, provides improved fit, structural integrity, and support, making these boots ideal for both sport and casual riders.
The rear of the heel counter features a soft Thermoplastic Rubber (TPR) insert seamlessly integrated with a flex zone, allowing for enhanced ankle mobility and comfort when operating motorcycle controls. The flex bellow with a dedicated air intake acts as a ventilation channel to promote airflow, keeping your feet cool and dry. An ergonomic TPU shift pad enhances durability in critical areas, ensuring long-lasting performance. The forefoot is streamlined through ergonomic shaping, offering a wide-ranging fit without sacrificing performance. The evolved closure system includes an anatomically angled strap with a TPR puller for ease of use, while Aramidic fiber wires ensure the system remains durable, lightweight, and reliable during aggressive riding.
The sole, crafted from Alpinestars' exclusive rubber compound, features a grip pattern designed to improve feel, grip, and water dispersion for enhanced safety and durability. Integrated with the Transversal Protection Frame (TPF), the sole provides superior protection against transversal loads. The boots’ instep and Achilles’ flex zones are built from lightweight microfiber, balancing durability, flexibility, and comfort both on and off the bike. Thermowelded flex grooves control flexion and movement, while the reverse zip closure offers quick entry and removal. Double-density ankle protectors layered beneath the upper provide abrasion resistance and impact protection in high-stress areas.
Additional features include a replaceable bi-injected TPU forefoot slider with a screw-fix system for quick replacement, external high modulus TPU heel counter, lateral ankle, and shift pad for shock absorption and durability. The internal toe box protection layer enhances durability and feel, complemented by a removable EVA foam and Lycra® foot-bed for comfort and support. An internal mesh lining ensures moisture-wicking and cooling comfort, making the Stella SMX-1R V2 boots a versatile choice for female riders demanding quality, protection, and comfort in their riding footwear.
