The Alpinestars SMX Plus motorcycle boots are designed for riders who want advanced protection, flexible movement, and a secure, performance-focused fit. This black, white, and red fluorescent model is sized for men's US 12 / EU 47 and features an advanced microfiber upper that helps reduce weight while providing excellent abrasion resistance and flexibility. The front flex area and Achilles accordion panel support natural forward, backward, and walking movement without compromising protective coverage.
Protection is provided by Alpinestars' Multi-Link Control system, which helps limit hyper-torsion, hyper-extension, and hyper-flexion of the ankle while adding support and impact protection around the Achilles and ankle. A contoured high-modulus shin plate improves impact and abrasion resistance, while dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider help protect key contact areas and promote controlled sliding during an accident. Large asymmetrical accordion zones further improve mobility and riding comfort.
The SMX Plus boots use a micro-adjustable ratchet top closure, inner instep speed lacing, and a lateral zipper for a precise, secure fit. Alpinestars Lace-Lock technology uses a polymer resin closure for quick adjustment, while the hook-and-loop tab secures the zipper pull. An advanced synthetic forefoot lining with open-cell foam provides shock absorption, and breathable ankle and leg lining helps improve comfort during extended rides. The anatomical, replaceable contoured EVA footbed offers arch support and pedal feel, while the durable textured rubber sole provides consistent grip. Manufactured by Alpinestars and identified by vendor part number 2221019-1231-47, these boots fit riders seeking a high-performance motorcycle boot for sport and street riding.
