The Alpinestars SMX Plus motorcycle boots are designed for riders seeking advanced protection, precise fit, and flexible performance on the street or track. This pair features an advanced microfiber upper with a soft microfiber front flex area to improve abrasion resistance while supporting natural forward and backward movement. Flexible accordion microfiber panels at the Achilles and exterior entry area provide comfort, mobility, and a close fit during riding.
Protection is built around Alpinestars Multi-Link Control system, which supports ankle articulation while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The boots also include Achilles and ankle impact protection, a contoured high-modulus shin plate, and dual-density TPU replaceable toe sliders with screw-in mounting. Replaceable heel and external side heel sliders help dissipate impact energy and encourage controlled sliding during an accident.
Fit and comfort features include large asymmetrical accordion zones, a micro-adjustable ratchet top closure, inner instep speed lacing, and a lateral zipper for secure adjustment and easy entry. The Alpinestars Lace-Lock System uses an advanced polymer resin closure for precise fastening, while a hook-and-loop tab keeps the zipper pull secured. An advanced synthetic forefoot lining with open-cell foam provides cushioning, and breathable ankle and leg lining helps improve comfort. The anatomical, replaceable contoured EVA footbed supports the arch and enhances forefoot pedal feel. A durable rubber sole provides consistent grip and riding feedback.
