The Alpinestars SMX-1 R V2 Riding Boots deliver low-cut performance, reliable protection, and comfortable control for street and sport riding. This black pair is sized for US 14 / EU 50 and features a lightweight, abrasion-resistant microfiber upper reinforced with strategically positioned thermoplastic polyurethane (TPU) protectors. The ergonomic shape streamlines the forefoot while accommodating a wide range of foot profiles for improved comfort on and off the motorcycle.
The SMX-1 R V2 uses an evolved closure system with an anatomically angled strap that follows the natural shape of the instep. A front hook-and-loop closure provides a secure, adjustable fit while allowing natural flex, and the integrated thermoplastic rubber puller makes adjustment easy. A reverse zipper supports convenient entry and removal, while the heel counter and strap work together to improve fit, support, and structural integrity. Thermowelded flex grooves and lightweight microfiber accordion zones at the instep and Achilles area help provide controlled movement in a variety of riding positions.
Protection is supported by double-density ankle protectors, an internal toe box, an external TPU heel counter, lateral ankle reinforcement, and an ergonomic TPU shift pad. The integrated Alpinestars Transversal Protection Frame helps guard against transversal loads, while the replaceable bi-injected TPU forefoot slider uses an easy-screw fixing design for efficient replacement. The rubber compound sole provides grip, water dispersion, durability, and dependable feel both on and off the bike.
Additional comfort features include a removable anatomical footbed with EVA foam and Lycra, plus an internal mesh lining that promotes cooling comfort and moisture management. The Alpinestars SMX-1 R V2 Riding Boots are designed for riders seeking a streamlined boot with everyday versatility, reinforced protection, and responsive control.
