The Alpinestars Tech 3 motorcycle boots are designed for off-road riders seeking reliable protection, comfort, and support in demanding riding conditions. This red, blue, and yellow fluorescent pair is sized for US 10 and EU 44.5 and is identified by Alpinestars manufacturer and vendor part number 2013018-3375-10. The flexible microfiber upper provides abrasion resistance while allowing comfortable movement, and the synthetic toe box adds durability in a high-wear area.
Protection: An extended polyurethane synthetic gaiter helps limit water and dirt entry, while the contoured thermoplastic polyurethane calf protector, higher medial protector, outer lateral ankle protector, and heel counter provide impact resistance and support. The injected TPU shin plate connects to the medial protector panel, and the rear thermoplastic rubber gaiter patch helps protect the rear flex area. A biomechanical medial blade system supports controlled front-to-rear flex at the ankle.
Fit and Closure: The ergonomic triple buckle system wraps around the front flex area without restricting movement. Three replaceable polymer buckles feature a memory ratchet, quick-release locking system, and self-aligning design for precise adjustment. A hook-and-loop upper closure with a thermoplastic rubber flap provides broad calf-fit adjustment. Soft foam around the ankle and collar enhances comfort and shock absorption, while the technical texture on the medial protector improves grip against the motorcycle.
Construction: The one-piece dual-compound TPU foot shell is reinforced with an internal metal shank and co-injected toe reinforcement. A replaceable EVA footbed with textile lining supports underfoot comfort, and the high-grip rubber compound outsole delivers dependable traction on varied terrain. The outsole is replaceable, helping extend the service life of these Alpinestars off-road boots.
