ALPINESTARS SMX-6 V3 Vented Boots

Built for demanding track and street riding, these vented motorcycle boots combine race-derived protection, performance-focused ergonomics, and all-day comfort. A precision-engineered design follows the anatomical contours of the foot to support flexibility, walking comfort, breathability, and precise control on the bike.

The advanced microfiber upper offers lightweight, high-performance abrasion resistance and flexibility, with laser-perforated areas for improved airflow. Air vents at the heel counter and shin plate, breathable mesh inserts, and perforated padding throughout the boot—including the front and rear bellows, collar, and ankle—help reduce fatigue and maintain comfort on short or long rides. Select variants feature a dedicated female fit for an optimized riding profile.

Front and rear flex zones combine textile, 3D mesh, and soft over-injected Thermoplastic Polyurethane (TPU) to enhance impact and abrasion resistance while allowing natural forward and backward foot movement. The evolved TPU ankle brace provides biomechanical support between the lateral calf, shin, and ankle, enabling superior ankle articulation while helping protect the Achilles and ankle from impacts.

Additional performance and protection features include:

• Alpinestars Lace-Lock System made from advanced polymer resin for quick, precise, and secure closure
• Medial side entry with an elastic-mounted zipper and wide hook and loop closure
• Ergonomic elastic gaiter for a precise fit in varying conditions
• Streamlined forefoot and contact surface for improved control and rider comfort
• Race-derived TPU shin plate protector for impact and abrasion resistance, with a compact profile that fits easily under riding pants
• TPU lateral ankle brace and lower medial TPU shifter zone for added protection
• Internal toe box protection layered beneath the upper for durability, feel, and performance
• Removable dual-compound anatomical EVA footbed with Lycra top layer
• Internal insole with integrated shank reinforcement for arch support and foot protection
• Lightweight rubber sole compound offering excellent grip on the pedal box
