The Alpinestars SMX-1 R v2 Motorcycle Riding Boots are low-cut performance boots designed for riders who want dependable protection, precise control, and comfortable movement on and off the motorcycle. This black and white model is sized for US 8 / EU 42 and features an advanced microfiber upper that combines lightweight comfort with strong abrasion resistance. Strategically positioned Thermoplastic Polyurethane (TPU) protectors reinforce the heel, ankles, shift area, and forefoot for enhanced coverage during street and sport riding.
The SMX-1 R v2 uses a quick, secure closure system with an anatomically angled hook-and-loop strap that follows the natural shape of the instep. A reverse zipper supports convenient entry and removal, while the heel counter and strap work together to improve fit, support, and structural integrity. Accordion flex zones at the instep and Achilles area, along with thermowelded flex grooves, promote controlled movement and rider comfort in a variety of riding positions. The rear flex bellow includes an airflow window to help improve ventilation around the ankle.
An exclusive Alpinestars rubber compound sole provides grip, water dispersion, and durability for confident footing on the bike and during walking. The sole incorporates the Alpinestars Transversal Protection Frame to help protect against transversal loads. An integrated, replaceable bi-injected TPU forefoot slider uses an easy-screw design for simplified replacement. Inside, the removable anatomical footbed combines EVA foam and Lycra for support, while the mesh lining helps manage moisture and maintain cooling comfort.
