The Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, combining advanced protection with lightweight flexibility. The microfiber upper construction ensures durability while maintaining a low weight, providing riders with a comfortable yet protective footwear option. The front flex area is crafted from soft microfiber that enhances abrasion resistance and allows natural movement forward and backward, crucial for control during aggressive riding. An accordion microfiber on the Achilles offers improved flexibility and natural ankle articulation, reducing fatigue during long rides or intense maneuvers. The outside entry features a stretchable accordion panel that ensures a snug fit, making it easy to put on and take off without sacrificing security.
The boots incorporate Alpinestars' innovative Multi-Link Control system, offering external protection and support for ankle articulation. This system limits hyper-torsion, hyper-extension, and hyper-flexion, shielding the ankle from impacts while allowing necessary mobility. Additional protective features include a dual-density TPU replaceable toe slider with a screw-in assembly for reliable impact coverage around the toes, along with replaceable heel sliders positioned to absorb shocks and facilitate sliding in case of a fall. Large asymmetrical accordion zones at the front and rear maximize flexibility and comfort, ensuring the boots adapt to various riding positions and movements.
Security and fit are enhanced through a micro-adjustable ratchet top closure with a stowable tab end, providing a customizable fit. The advanced synthetic lining in the forefoot is laminated with open-cell foam, offering superior shock absorption and breathability, while the ankle and leg areas feature highly breathable materials for long-lasting comfort. The anatomical, replaceable EVA footbed delivers arch support and a precise pedal feel, crucial for control and stability. The sole is designed for optimal grip, with textured rubber that ensures consistent contact with the footpegs. Inner instep speed lacing closure paired with a lateral zipper allows for a secure, personalized fit, while the Alpinestars Lace-Lock System ensures quick and reliable tightening. A hook-and-loop tab locks the zipper pull in place, preventing accidental opening during rides. The boots are further reinforced with a contoured high-modulus shin plate that provides superior impact and abrasion resistance, making the SMX Plus a versatile choice for sportbike riders seeking protection, comfort, and performance.
