The Alpinestars SMX Plus Motorcycle Boot is a sleek sports boot with advanced levels of protection. This is a race-proven boot, and the whole boot is CE-certified. Alpinestars' exclusive Multi Link Control (MLC) system helps prevent ankle torsion and hyperextension while offering freedom of movement and adding impact protection to critical ankle areas. Medial-side contouring of the boots promotes greater contact with the body of the bike for a comfier and greater ride. Replaceable, dual-density advanced polymer toe-sliders, moulded ankle protectors, a high-density TPU rear heel-plate slider and a reinforced shock-absorbing heel counter, protect and reduce friction in the event of a crash. The upper is constructed from lightweight and durable Microfibre with anatomically optimised, asymmetric leather accordion zones and a strategically positioned front vent for for maximum flexibility and riding comfort. The contoured synthetic compound sole features aqua-dynamic channels to promote greater water run-off. A speed lacing closure, elastic-mounted lateral zipper and ratchet buckle closure on the calf ensure a precise and secure fit. The Alpinestars anatomical footbed provides arch support and improved forefoot feeling. This colourway is exclusive to J&S Accessories in the UK.
