The Alpinestars SMX-1 R v2 Riding Boots combine low-cut performance with everyday comfort, protection, and control for street and sport riding. This black riding boot is sized US 10.5 / EU 45 and features an advanced microfiber upper that is lightweight, durable, and abrasion resistant. Strategically positioned Thermoplastic Polyurethane (TPU) protectors reinforce the heel, ankles, shift area, and forefoot, while the internal toe box and double-density ankle protection add support in critical impact zones.
The SMX-1 R v2 uses an anatomically angled Velcro® closure strap with an easy-pull Thermoplastic Rubber (TPR) tab for a secure, adjustable fit over the instep. Aramidic fiber wires help keep the closure system thin, lightweight, and durable. A reverse zipper provides convenient entry and removal, while the innovative heel counter support system works with the strap to improve fit, stability, and structural integrity. Accordion flex zones at the instep and Achilles area, along with thermowelded flex grooves, provide controlled movement and comfort on and off the motorcycle.
An Alpinestars exclusive compound rubber sole delivers dependable grip, water dispersion, and durability. The sole incorporates the Alpinestars Transversal Protection Frame (TPF) to help protect against transversal loads without restricting natural foot movement. An integrated, replaceable bi-injected TPU forefoot slider uses an easy-screw design for efficient replacement. The removable anatomical footbed combines EVA foam and Lycra® for cushioning and support, while the internal mesh lining helps wick moisture and maintain cooling airflow. The Alpinestars SMX-1 R v2 Riding Boots are supplied under manufacturer part number 2224521-10-45 and vendor part number 2224521-10-45.
