The Alpinestars Tech 3 Boots are designed for off-road motorcycle riders seeking dependable protection, comfort, and control. This black pair is sized for US 11 / EU 45.5 and features a lightweight microfiber upper that provides flexibility with strong abrasion resistance. Microfiber panels at the front and rear flex areas improve comfort while allowing natural movement, while the synthetic toe box is built to withstand repeated abrasion.
Protection is provided by an extended polyurethane gaiter that helps limit water and dirt entry, along with a contoured thermoplastic polyurethane calf protector, higher medial protector, outer lateral ankle protector, and heel counter. An injected TPU shin plate connects with the medial protector panel for integrated lower-leg coverage. The rear thermoplastic rubber gaiter patch adds comfort and protection during rear flexing, while the Bio-mechanical medial blade system supports controlled front-to-rear ankle movement.
The ergonomic triple-buckle closure system uses three replaceable polymer buckles with memory ratchets, quick-release locking, and self-aligning operation for easy, precise adjustment. A hook-and-loop upper closure with a thermoplastic rubber flap accommodates a broad range of calf sizes. The one-piece dual-compound TPU foot shell includes a metal shank and co-injected toe reinforcement for added structural support. Soft ankle and collar foam helps absorb shock, and the replaceable EVA footbed has a textile lining for improved comfort.
A high-grip rubber compound outsole delivers traction for off-road riding and is replaceable when needed. Manufactured by Alpinestars and identified by manufacturer and vendor part number 2013018-10-11, these Tech 3 Boots provide versatile fitment for riders wearing US men's size 11 / EU 45.5 motorcycle footwear.
