The Alpinestars SMX-6 V3 Vented Boots are race-inspired motorcycle riding boots designed for track and street use. This black, silver, and red model is sized US 8 / EU 42 and features an advanced microfiber upper with laser-perforated panels for a balance of abrasion resistance, flexibility, and airflow. The boot's ergonomic construction follows the natural contours of the foot to support precise control, comfortable walking, and reduced fatigue during short or extended rides.
Protection is built into every major performance area. A TPU ankle brace provides biomechanical support between the calf, shin, and ankle while helping protect the Achilles and ankle from impact. A race-derived TPU shin plate and TPU shifter zone add targeted protection, while layered internal toe protection helps preserve durability and rider feel. Front and rear flex zones combine textile, 3D mesh, and soft TPU to encourage natural movement while resisting impact and abrasion. Air vents in the heel counter and shin plate, breathable mesh inserts, and perforated padding throughout the boot enhance ventilation.
The Alpinestars Lace-Lock System uses a polymer resin closure for quick, precise, and secure adjustment. A medial-side elastic-mounted zipper and wide hook-and-loop closure simplify entry and provide a reliable fit, while the ergonomic elastic gaiter helps seal the opening. A removable dual-compound EVA footbed with Lycra lining and an internal shank reinforcement support the foot and arch. The lightweight rubber sole delivers dependable grip on the foot controls, and the streamlined forefoot improves contact and control on the motorcycle.
