The Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, combining advanced protection with superior comfort. Featuring an innovative microfiber upper construction, these boots offer a lightweight yet durable barrier that adapts to the rider's movements. The front flex zone is crafted with soft microfiber to enhance abrasion resistance while allowing natural forward and backward motion, reducing fatigue during long rides. The flexible accordion microfiber on the Achilles area further improves natural movement, ensuring the rider maintains full control and agility. An external stretchable accordion panel at the entry point provides a snug fit, making it easier to put on and take off the boots without sacrificing security.
Alpinestars has evolved its signature Multi-Link Control system in the SMX Plus, delivering advanced external protection and support for ankle articulation. This system limits hyper-torsion, hyper-extension, and hyper-flexion, effectively reducing injury risk during aggressive riding or accidents. It also offers enhanced Achilles and ankle impact protection. The boots are equipped with a dual-density Thermoplastic Polyurethane (TPU) replaceable toe slider with a screw-in assembly, providing robust coverage around the outer toe for added safety. The replaceable heel slider and external side heel slider are strategically positioned to absorb shocks and facilitate sliding during a fall, minimizing injury.
Design features large, asymmetrical accordion zones at the front and rear, optimized to maximize flexibility and comfort while maintaining safety standards. The micro-adjustable ratchet top closure with a stow tab end ensures a secure, customized fit. The advanced synthetic forefoot lining, laminated with open cell foam, provides excellent shock absorption, while the highly breathable lining in the ankle and leg areas enhances overall comfort. An anatomical, replaceable EVA footbed offers arch support and a tactile feel for the pedal, ensuring precise control. The durable sole is textured rubber, designed for optimal grip and riding feel. Additional features include inner instep speed lacing closure, a lateral zipper for a secure fit, and the Alpinestars Lace-Lock System, made from advanced polymer resin, allowing quick, precise, and secure fastening.
To ensure safety and stability, the boots feature a contoured high-modulus shin plate protector that resists impacts and abrasions. Hook-and-loop straps lock the zipper pull in place, maintaining a flat, secure closure. With a focus on durability, comfort, and protective features, the Alpinestars SMX Plus boots are an excellent choice for riders seeking high-level safety and performance in a versatile riding boot.
