Alpinestars Tech 3 Boots — EU 43, Over-Calf, Gray

Tech 3 boots combine race-proven protection with lightweight construction to deliver reliable off-road performance and comfort. Designed for aggressive riding, they offer multi-panel TPU protection, a co-injected foot shell with metal shank reinforcement, and a biomechanical medial blade system to support ankle flex while absorbing impacts.

• Innovative lightweight microfiber upper and front/rear bellows for increased flexibility and abrasion resistance.
• Reinforced synthetic toe box and co-injected toe reinforcement for high abrasion zones.
• Contoured TPU calf plate, higher medial protector, lateral ankle and heel counter for robust impact resistance.
• Injected TPU shin plate with hook-and-loop upper closure and TPR flap for broad calf adjustment.
• Triple replaceable polymer buckles with ratchet memory, quick-release and self-aligning design for precise closure.
• One-piece injected dual compound TPU foot shell with internal metal shank and replaceable high-grip rubber outsole; removable EVA footbed with textile lining.

Soft ankle and collar foams improve comfort while rear TPR gaiter patches and extended PU gaiter help seal out water and dirt. The technical texture on the medial protector enhances grip and the ergonomic buckle straps wrap the boot without compromising flex.
