Alpinestars SMX-1 v2 Riding Boots - Black/White, US 8 / EU 42, Part 2224521-12-42

The Alpinestars SMX-1 v2 riding boots are engineered for high-performance motorcycling, combining advanced materials and innovative design features to deliver superior comfort, fit, and durability. Constructed with a lightweight, abrasion-resistant microfiber upper, these boots provide essential protection while maintaining flexibility for optimal riding control. Strategically placed Thermoplastic Polyurethane (TPU) protectors reinforce critical areas such as the heel, ankle, and shift zone, enhancing impact resistance and structural integrity. The rubber compound sole features an advanced grip pattern for excellent traction on and off the bike, complemented by integrated Alpinestars Transversal Protection Frame (TPF) to safeguard against transversal loads, ensuring rider safety in demanding conditions.
The ergonomic shaping of the boot, including a forefoot streamlining design, offers a comfortable fit for a wide range of foot profiles. The evolved closure system combines an anatomically angled strap with a quick, secure Velcro® front closure for ease of use and optimal fit. The strap features a Thermoplastic Rubber (TPR) puller for quick adjustments, while durable Aramidic fiber wires reinforce the closure's longevity. Accordion flex zones at the instep and Achilles’ areas provide enhanced flexibility and maneuverability, supporting dynamic riding positions.
Ventilation and airflow are optimized through flex grooves and a rear flex bellow with a flex window that also acts as an air intake. The internal toe box and ankle protectors are layered under the upper for added durability and abrasion resistance. The external TPU heel counter, lateral ankle, and shift pad improve shock absorption and durability, while the heel counter's soft TPR insert offers increased ankle mobility and comfort. The removable, anatomically designed foot-bed features EVA foam and Lycra® for additional support and cushioning, and the internal mesh lining promotes moisture-wicking and cooling comfort during long rides.
For convenience and easy maintenance, the boots include an integrated, replaceable bi-injected TPU forefoot slider with a user-friendly screw fixing system. Overall, the Alpinestars SMX-1 v2 boots are a top choice for riders seeking a combination of high-level protection, comfort, and performance, suitable for both casual and aggressive riding styles.
