The Alpinestars Stella SMX-1R V2 boots are designed to provide women riders with a high-performance, comfortable, and durable footwear solution tailored to an anatomically optimized fit. Crafted from an advanced microfiber upper, these boots offer excellent abrasion resistance and long-lasting comfort, making them suitable for both aggressive riding and everyday use. The innovative heel counter support system works in tandem with a strap closure to enhance fit, support, and structural integrity, ensuring confidence during dynamic riding conditions. The rear of the heel counter features a soft Thermoplastic Rubber (TPR) insert that seamlessly integrates with the rear flex zone, allowing for enhanced ankle mobility and comfort when operating bike controls. Ventilation is optimized through a flex window in the rear flex bellow, which functions as an air intake, promoting airflow and keeping the rider’s feet cool during extended rides. The boots incorporate a new ergonomic Thermoplastic Polyurethane (TPU) shift pad in critical areas for increased durability and protection. An anatomically shaped boot profile ensures a wide-ranging fit for various foot shapes, providing optimal comfort and control. The evolved closure system includes an angled strap to follow the natural contours of the rider’s instep, combined with a quick-acting Velcro® closure over the instep and a TPR puller for ease of use. Aramidic fiber wires reinforce the strap closure system, making it lightweight yet durable. The exclusive Alpinestars rubber sole features a grip pattern designed to enhance feel, grip, and durability, with integrated Transversal Protection Frame (TPF) to guard against transversal loads. Light microfiber is used in the instep and Achilles’ flex zones for flexibility, comfort, and maneuverability both on and off the bike. Flex grooves are thermowelded into the sole to control flexion, while a reverse zip closure allows for easy entry and removal. Double density ankle protectors layered under the upper provide abrasion resistance and impact protection. The boots also feature a replaceable, bi-injected TPU forefoot slider with a quick-screw fixing system for easy maintenance. External high-modulus TPU heel counters, lateral ankle protectors, and shift pads add shock absorption and durability, while internal toe box protection enhances overall resilience. The removable anatomic foot-bed, made of EVA foam and Lycra®, offers added comfort and support, complemented by an internal mesh lining that wicks moisture and promotes cooling. These boots combine innovative design, advanced materials, and ergonomic features to meet the demands of female motorcyclists seeking performance, protection, and comfort in a sleek package.
