The Alpinestars SMX-1 R v2 Riding Boots provide lightweight, low-cut performance for street and sport riders seeking dependable protection, comfort, and control. This black and red boot is sized for US 13.5 / EU 49 and features an abrasion-resistant microfiber upper reinforced with strategically positioned thermoplastic polyurethane (TPU) protectors. The ergonomic shape supports a broad range of foot profiles while maintaining a streamlined feel for use on motorcycles or while walking off the bike.
Designed for secure fitment and easy movement, the SMX-1 R v2 uses an anatomically angled hook-and-loop closure strap that follows the natural shape of the instep. A thermoplastic rubber puller and aramidic fiber reinforcement help provide durable, lightweight operation. Accordion flex zones at the instep and Achilles area, along with thermowelded flex grooves, support natural ankle movement and rider control. The reverse zipper closure makes the boots convenient to put on and remove, while the internal mesh lining helps manage moisture and airflow.
Protection includes double-density ankle protectors, an internal toe box, an external TPU heel counter, a lateral ankle protector, and a durable TPU shift pad. The Alpinestars Transversal Protection Frame is integrated into the rubber compound sole to help resist transversal loads. A replaceable, bi-injected TPU forefoot slider uses an easy-screw fixing system for efficient replacement. The exclusive Alpinestars rubber sole provides grip, water dispersion, and durability on and off the motorcycle. A removable anatomic footbed with EVA foam and Lycra supports comfort during extended rides.
