The Alpinestars Tech 3 Boots are designed for motocross and off-road riding, offering a blend of track-proven performance technologies with an anatomically profiled design for protection and comfort. These boots feature a durable yet lightweight main shell, with comprehensive protection both inside and out. Constructed from light microfiber for enhanced flexibility, durability, and abrasion resistance, the boots include front and rear bellows for improved comfort and flexibility. A synthetic material toe cap provides abrasion resistance. The upper features a PU synthetic gaiter to prevent water and dirt ingress. Protection is enhanced by TPU calf, medial, outer ankle, and heel counters for support and shock resistance. A rear TPR gaiter adds protection and comfort during heel flex. The injected TPU shin plate integrates with the medial protection panel, and the top closure uses a hook-and-loop strap with a TPR flap to accommodate various calf sizes. The higher TPU medial protector has a technical texture for improved grip. A biomechanical blade system offers progressive front and rear flexion, supporting the ankle. The ergonomic triple buckle closure system, made of polymer, ensures easy and precise fastening with a micro-adjustable, memory-setting ratchet and a quick-release/auto-aligning closure. All buckles are replaceable. The boot includes an innovative, one-piece injected TPU dual-density sole, reinforced with a metal shank and co-injected toe cap. Soft foam surrounds the ankles and boot top for comfort and shock absorption. A full fabric inner lining enhances comfort and moisture management. The removable EVA insole with a comfort footbed provides arch support. The exclusive Alpinestars rubber compound outsole ensures grip and traction on various surfaces, with an anatomical design for control and sensitivity on the footpegs. The sole is replaceable. The TECH 3 boots are CE certified to EN 13634:2010.
