The Alpinestars SMX-1 R v2 Riding Boots are low-cut performance motorcycle boots designed for riders who want dependable protection, comfort, and control both on and off the bike. This black and red model is offered in US men's size 6 / EU 39 and features a lightweight, 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 forefoot for improved comfort and control.
Designed for sport and street riding, the SMX-1 R v2 uses Alpinestars' exclusive compound rubber sole with a grip-focused pattern for traction, water dispersion, durability, and improved rider feel. An integrated Transversal Protection Frame helps protect against transversal loads, while the replaceable bi-injected TPU forefoot slider uses an easy-screw fixing design for convenient replacement. External TPU protection at the heel, ankles, and shift area adds impact and abrasion resistance in key zones.
Comfort and mobility are supported by accordion flex zones at the instep and Achilles area, thermowelded flex grooves, a rear flex bellow with an airflow window, and a reverse zip closure for easy entry and removal. The anatomically angled closure strap follows the natural shape of the instep and uses a secure hook-and-loop fastening system with a durable thermoplastic rubber puller. A removable anatomical footbed with EVA foam and Lycra, along with an internal moisture-wicking mesh lining, helps provide support and cooling comfort during extended rides.
Manufactured by Alpinestars, the SMX-1 R v2 Riding Boots carry vendor and manufacturer part number 2224521-13-39. They are designed to fit riders seeking a low-profile motorcycle boot for street, sport, and everyday riding applications.
