Alpinestars SMX-6 V3 Racing Motorcycle Boots - Black US 9 / EU 43, Part 2223025-10-43

The Alpinestars SMX-6 V3 boots offer a comprehensive blend of safety, performance, and durability designed for both track racing and street riding. Crafted with an advanced microfiber upper, these boots deliver lightweight protection against abrasion while maintaining impressive flexibility for natural movement. The strategic construction features front flex and back flexion zones, over-injected with soft Thermoplastic Polyurethane (TPU), enhancing impact resistance and promoting a smooth, forward-backward motion during riding. These zones help prevent injuries by absorbing shocks and reducing strain on key areas of the foot and ankle.

The boot's ankle brace protection system integrates biomechanical support, providing superior articulation and stability at the ankle while limiting hyper-torsion, hyper-extension, and hyper-flexion. This system also offers impact protection for the Achilles and ankle, ensuring rider safety in demanding conditions. The innovative Lace-Lock System, made from durable polymer resin, guarantees quick, precise, and secure closure for a personalized fit that stays in place throughout rides.

Additional protective features include a TPU shifter zone for enhanced durability on the lower medial side and a race-derived TPU shin plate that delivers excellent impact and abrasion resistance. Dual density TPU ankle protectors are located between the upper and padded lining, strategically positioned to shield critical areas. The replaceable dual density TPU toe slider with screw-in assembly provides comprehensive protection around the outer toe while maintaining walking comfort. The heel sliders, both replaceable and external side, are designed for optimal shock absorption and sliding in the event of a fall, reducing injury risk and promoting safety during aggressive riding. Overall, the Alpinestars SMX-6 V3 boots are engineered for riders seeking high-performance footwear that combines advanced safety features with exceptional comfort and flexibility.
