The Alpinestars SMX Plus Boots are engineered for high-performance motorcycling, combining advanced protection with superior comfort. Featuring an innovative microfiber upper construction, these boots are lightweight yet durable, providing excellent abrasion resistance and flexibility for aggressive riding. The front flex zone employs soft microfiber to enhance natural movement and reduce fatigue, while the accordion microfiber on the Achilles area allows for improved articulation and comfort during extended wear. An external stretchable accordion panel ensures a snug fit and effortless entry and exit, streamlining the riding experience.
The boots incorporate Alpinestars' Multi-Link Control system, which offers enhanced external support for ankle articulation, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion. This system also delivers critical impact protection around the Achilles and ankle regions. Protective features are further bolstered by the dual-density Thermoplastic Polyurethane (TPU) toe sliders, which are screw-in and replaceable, providing reliable coverage for the outer toe area. The heel sliders are also replaceable and positioned to absorb shocks and facilitate sliding during accidents, enhancing rider safety.
Large asymmetrical accordion zones at the front and rear maximize flexibility, ensuring comfort without compromising safety. The boots are equipped with a micro-adjustable ratchet top closure with a stow tab end for a secure fit. The advanced synthetic forefoot lining, laminated with open-cell foam, offers shock absorption and breathability, keeping feet comfortable and dry. Additionally, the ankle and leg areas feature a highly breathable lining for increased comfort during long rides. The anatomically designed EVA footbed is replaceable and provides arch support and a firm pedal feel, critical for precise control. The sole is textured rubber, designed to improve grip and riding feedback, while the inner instep speed lacing system and lateral zipper allow for a customized, secure fit.
The innovative Lace-Lock System, made from advanced polymer resin, ensures quick and secure fastening, complemented by hook-and-loop tabs that keep the zipper flat and secure. The contoured high-modulus shin plate offers superior impact and abrasion resistance, protecting vital areas during aggressive riding. These features make the Alpinestars SMX Plus Boots a top choice for riders seeking a blend of protection, performance, and comfort in a premium motorcycle boot.
