The Alpinestars SMX-1 R v2 Riding Boots deliver low-cut sport performance for riders seeking a balance of protection, comfort, and control. Designed in Black/Red for a US 5 / EU 38 fit, these boots feature 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 a secure, comfortable fit on and off the motorcycle.
Alpinestars’ anatomically angled strap closure follows the natural shape of the instep and works with the reverse zipper to provide convenient entry and a precise fit. The front hook-and-loop closure allows excellent flex, while the Thermoplastic Rubber puller and aramidic fiber reinforcement support quick, durable adjustment. Accordion flex zones at the instep and Achilles, along with thermowelded flex grooves, promote natural movement and control in a variety of riding positions. The rear flex bellow also incorporates an airflow window for added ventilation.
Protection is provided by double-density ankle protectors, an external high-modulus TPU heel counter, a TPU lateral ankle protector, an ergonomic TPU shift pad, and internal toe box reinforcement. The integrated replaceable bi-injected TPU forefoot slider uses Alpinestars’ easy-screw fixing concept for efficient replacement. The exclusive compound rubber sole features a high-traction pattern for grip, water dispersion, and durability, while the integrated Alpinestars Transversal Protection Frame helps protect against transversal loads. A removable anatomical footbed with EVA foam and Lycra, combined with an internal moisture-wicking mesh lining, enhances everyday comfort.
