Alpinestars SMX Plus Motorcycle Boots Black/White/Red Fluorescent US 9.5 / EU 44 - Part 2221019-1231-44

Designed for high-performance motorcycling, the Alpinestars SMX Plus Boots offer advanced protection and superior comfort for riders seeking durability and agility. The microfiber upper construction ensures lightweight strength while maintaining flexibility, allowing for natural movement and enhanced control during rides. The innovative front flex zone, crafted from soft microfiber, improves abrasion resistance and permits smooth forward and backward motion, making these boots suitable for aggressive riding styles. The flexible accordion microfiber on the Achilles area supports natural flexion, reducing fatigue during extended use, while the stretchable accordion panel on the outside entry ensures a snug fit and easy on-and-off operation.
Alpinestars' unique Multi-Link Control system provides external support and protection for the ankle, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion movements. This system enhances ankle articulation and absorbs impact, offering increased safety without compromising mobility. The durable sole, made from textured rubber, ensures consistent grip and riding feel, essential for both street and track use. The front and rear accordion zones are optimized for maximum flexibility, promoting comfort and safety during dynamic riding conditions.
Additional protective features include a replaceable, screw-in toe slider, and external heel sliders designed to dissipate shock and facilitate sliding in the event of a fall. The boots feature a micro-adjustable ratchet top closure with a stow tab, a lateral zipper for precise fit adjustments, and an Alpinestars Lace-Lock System made from advanced polymer resin for quick, secure closure. The high-modulus shin plate offers superior impact and abrasion resistance, while the laminated synthetic forefoot lining with open-cell foam provides shock absorption and breathability. The anatomically designed, replaceable EVA footbed supports the arch and enhances pedal feel, ensuring comfort during long rides and demanding maneuvers.
Engineered for safety, comfort, and performance, the Alpinestars SMX Plus Boots are an excellent choice for serious motorcyclists. Whether navigating city streets or tackling the open road, these boots deliver reliable protection, precise fit, and exceptional durability, making them a valuable addition to any rider’s gear collection.
