The ALPINESTARS Tech 3 Boots in US 13 / EU 48 are designed with a flexible, abrasion-resistant microfiber upper for comfort and durability. Light microfiber panels at the front and rear bellows support flexibility, while the synthetic toe box is designed for high abrasion resistance. An extended polyurethane synthetic gaiter helps limit excessive water and dirt entry.
Protection features include a contoured thermoplastic polyurethane calf protector plate, higher medial protector, outer lateral ankle protector, heel counter, and injected TPU shin plate. A biomechanical medial blade system supports front-to-rear flex and ankle protection, while the rear thermoplastic rubber gaiter patch adds protection and comfort during rear flex. Soft foam around the ankles and collar provides cushioning and shock-absorbing performance.
The closure system uses three polymer buckles with ratchet memory, quick-release and locking functions, and a self-aligning design for precise closure. The buckles are replaceable. A hook-and-loop upper closure with a TPR flap allows broad calf-fit adjustment. The one-piece dual-compound TPU foot shell includes a metal shank and co-injected toe reinforcement. Additional features include a replaceable EVA footbed with textile lining and a replaceable high-grip rubber compound outsole. Manufacturer and vendor part number: 2013018-3375-13.
