The Alpinestars SMX Plus motorcycle boots deliver advanced protection, flexibility, and precise fit for performance-oriented street and track riding. This black, white, and red fluorescent model is sized at US 6.5 / EU 40 and features an advanced microfiber upper designed to provide lightweight durability and excellent abrasion resistance. Soft microfiber flex areas and accordion panels at the Achilles, front, rear, and outer entry zones support natural forward and backward movement while maintaining a secure, close-fitting profile.
An evolution of Alpinestars’ Multi-Link Control system provides external ankle support and protection while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The contoured high-modulus shin plate, dual-density TPU toe slider, replaceable heel slider, and external side heel slider help protect key impact zones and promote controlled sliding during an accident. The toe and heel sliders are replaceable, supporting long-term serviceability for frequent riders.
Comfort and closure performance are supported by an inner instep speed-lacing system, a lateral zipper, Alpinestars Lace-Lock System, and a micro-adjustable ratchet top closure. The zipper pull is secured with a hook-and-loop tab, while the breathable lining and open-cell foam provide cushioning throughout the ankle and leg areas. An anatomical, replaceable contoured EVA footbed supports the arch and enhances pedal feel. The durable rubber sole supplies consistent grip and riding feedback.
