Alpinestars SMX Plus Motorcycle Boots - Black/White/Red Fluorescent, US 10.5 / EU 45, Part Number 2221019-1231-45

The Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, combining advanced protection with superior comfort. Constructed with a lightweight microfiber upper, these boots provide excellent abrasion resistance and flexibility, enabling natural movement during aggressive riding or long-distance journeys. The front flex zone, made from soft microfiber, enhances forward and backward mobility, while the accordion microfiber on the Achilles area offers additional flexibility and support for natural ankle articulation. An external stretchable accordion panel at the entry point ensures a snug fit and effortless donning and removal, making these boots both practical and comfortable.
Alpinestars' innovative Multi-Link Control system offers external ankle protection by limiting hyper-torsion, hyper-extension, and hyper-flexion movements. This system delivers exceptional ankle support while safeguarding the Achilles and ankle from impacts. The boots feature dual-density TPU replaceable toe sliders with screw-in assemblies, providing durable protection around the toes and allowing easy replacement after wear. Additional impact absorption is facilitated by replaceable heel and side sliders, positioned to dissipate shock during accidents and promote sliding to reduce injury risk.
The design emphasizes maximum flexibility with large asymmetrical accordion zones on the front and rear, optimizing comfort and safety. The micro-adjustable ratchet closure system ensures a secure fit, with a stowable tab for convenience. The advanced synthetic lining in the forefoot, laminated with open-cell foam, offers shock absorption, while breathable materials in the ankle and leg areas maintain comfort during extended rides. An anatomical EVA footbed, which is also replaceable, provides arch support and a tactile pedal feel, enhancing rider control.
The sole is crafted for durability and grip, featuring a textured rubber surface that delivers consistent traction on various surfaces. Inner instep speed lacing combined with a lateral zipper allows for precise fit adjustments and quick removal. The Alpinestars Lace-Lock System, made from advanced polymer resin, secures the laces firmly for added safety. A hook-and-loop tab locks the zipper pull in place, preventing accidental opening. Additional protection is provided by a contoured high-modulus shin plate, offering excellent impact and abrasion resistance, making these boots ideal for demanding riding conditions and competitive environments.
