The Alpinestars SMX-6 V3 boots are engineered for riders who demand high performance and safety on both the track and street. Featuring an advanced microfiber upper construction, these boots offer lightweight protection against abrasion while maintaining excellent flexibility for natural movement. The innovative design incorporates front flex and back flexion zones, crafted with textile over-injected with soft Thermoplastic Polyurethane (TPU), enhancing impact resistance and promoting a smooth, unrestricted range of motion. This combination ensures that riders can focus on their performance without compromising safety. The boots are equipped with Alpinestars' unique ankle brace protection system, providing biomechanical support and superior articulation between the calf, shin, and ankle. This system helps limit hyper-torsion, hyper-extension, and hyper-flexion movements while offering additional impact protection for the Achilles and ankle areas. The integrated Lace-Lock System uses an advanced polymer resin to deliver quick, precise, and secure closure, ensuring a perfect fit during aggressive riding. For added protection in high-impact zones, the SMX-6 V3 features a TPU shifter zone on the lower medial side, as well as a race-derived TPU shin plate that resists impact and abrasion. Dual density TPU ankle protectors are strategically positioned between the upper and padded lining to safeguard key areas, enhancing overall durability. The boots also include replaceable dual density TPU toe sliders with a screw-in assembly, providing robust coverage around the outer toe while remaining flexible enough for walking comfort. Additional protection is provided by replaceable heel sliders and external side heel sliders, designed for shock absorption and to promote sliding in the event of a fall, reducing injury risk. These boots are an ideal choice for serious riders seeking a combination of advanced safety features, durability, and performance-oriented design in a sleek black finish.
