Alpinestars SMX-6 V3 Motorcycle Racing Boots - Black, US 12 / EU 47 (Part Number 2223025-10-47)

The Alpinestars SMX-6 V3 boots are engineered for riders seeking high-performance protection on both the track and street. Crafted with an advanced microfiber upper, these boots offer lightweight durability, exceptional abrasion resistance, and flexibility for dynamic riding movements. The design incorporates strategic flex zones with textile and thermoplastic polyurethane (TPU), providing enhanced impact absorption and allowing natural forward and backward motion for rider comfort and agility. These features ensure that riders can maintain precision control during aggressive maneuvers while feeling protected at all times.
Alpinestars has integrated a comprehensive ankle brace system that delivers biomechanical support, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion. This system also offers superior protection for the Achilles tendon and ankle, reducing injury risk during impacts or falls. The Lace-Lock System, made from an advanced polymer resin, ensures quick, secure, and precise closure, giving riders confidence in their fit and safety. Additional protective elements include a TPU shifter zone on the lower medial side for durability and a race-derived TPU shin plate for superior impact and abrasion resistance.
Strategically placed dual-density TPU protectors on the ankle, heel, and external side of the heel absorb shocks and facilitate sliding in case of a fall, minimizing injury. The replaceable dual-density TPU toe slider, secured with a screw-in assembly, offers comprehensive coverage without sacrificing walking comfort. The heel sliders, both external and internal, are positioned to dissipate shock effectively and promote controlled sliding during accidents, enhancing rider safety. These boots are designed with rider needs in mind, combining innovative materials and protective features to deliver a high level of safety, comfort, and performance for motorcycle enthusiasts and racers alike.
