The Alpinestars Tech 3 Motorcycle Boots combine lightweight microfiber construction, impact protection, and flexible support for off-road and motocross riding. This red, blue, and yellow fluorescent model is sized for US 9 and EU 43 and is identified by manufacturer and vendor part number 2013018-3375-9. The abrasion-resistant microfiber upper provides flexibility, while reinforced synthetic material at the toe box helps protect against wear in high-contact areas.
Protection: Contoured thermoplastic polyurethane (TPU) calf, medial ankle, lateral ankle, heel, and shin components help resist impacts and support the lower leg. A TPU-injected dual-compound foot shell is reinforced with an internal metal shank and co-injected toe reinforcement. An extended polyurethane gaiter helps limit the entry of water and dirt, while a thermoplastic rubber rear gaiter patch protects the flex area and improves comfort.
Fit and Closure: A hook-and-loop upper closure with a thermoplastic rubber flap allows calf-fit adjustment and support. The ergonomic triple-buckle system follows the boot’s front flex from the medial to lateral side without restricting movement. Three replaceable polymer buckles use memory ratchets, quick-release locking, and self-aligning hardware for precise closure. Soft foam around the ankle and collar helps cushion the foot and improve comfort during extended riding.
Riding Performance: The biomechanical medial blade system supports controlled front-to-rear flex while helping protect the ankle. A textured TPU medial protector enhances grip against the motorcycle. The replaceable EVA footbed features a textile top lining, and the high-grip rubber compound outsole provides traction on varied off-road surfaces. The sole is replaceable for practical long-term service. Manufacturer: Alpinestars. Vendor part number: 2013018-3375-9.
