The Alpinestars SMX Plus Boots perfectly blend sleek sports styling with advanced protection features developed in Alpinestars' performance footwear department. Constructed with an advanced microfiber upper, these boots offer lightweight, high-performance protection and superb levels of flexibility for demanding riders.
For superior safety, the boots feature an evolution of the unique Multi-Link Control system. This provides advanced external protection and support for ankle articulation, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion while providing critical impact protection to the Achilles and ankle. A contoured high modulus shin plate protector offers excellent impact and abrasion resistance, while the dual density Thermoplastic Polyurethane (TPU) replaceable toe slider ensures comprehensive coverage around the outer toe area. Additionally, replaceable heel sliders are strategically positioned to dissipate shock and promote sliding during an accident.
Comfort and feel are prioritized through large front and rear asymmetrical accordion zones, optimized to maximize flexibility and natural movement. The inner instep features a speed lacing closure made from advanced polymer resin, combined with a unique lateral zipper for a precise and secure fit. A micro-adjustable ratchet top closure allows for further customization, while the hook and loop tab locks the zip pull flat and safe.
Internal features include an advanced synthetic forefoot lining laminated with open-cell foam for shock absorption, alongside a highly breathable lining in the ankle and leg areas. The anatomical and replaceable contoured EVA footbed provides essential arch support and enhanced pedal feel. The durable rubber sole is designed with an even texture for consistent grip and improved riding feedback.
