Alpinestars Tech 3 Boots — EU 40.5, Over‑Calf, Gray/Black

The Tech 3 boots blend advanced protection and flexible performance for off‑road riding. Upper construction uses innovative, lightweight microfiber that resists abrasion while allowing mobility. Contoured TPU plates at the calf, medial, lateral ankle and heel counter provide reliable impact resistance, and a rear TPR gaiter patch protects the boot during rear flex.

Comfort features include soft foams around the ankle and collar, a replaceable EVA footbed with textile lining, and a one‑piece injected TPU dual‑compound foot shell reinforced by a metal shank and co‑injected toe reinforcement. The ergonomic triple buckle straps, ratchet memory and quick‑release system deliver precise, repeatable closure; all buckles are replaceable.

Additional technical details: a bio‑mechanical medial blade allows controlled fore‑to‑aft flex; injected TPU shin plate integrates with the medial protector panel; front and rear bellows use light microfiber for improved comfort; the high‑grip rubber outsole is replaceable.

Designed for riders who demand durable protection without sacrificing mobility, the Tech 3 boots offer balanced support, advanced closure technology, and serviceable components to extend the life of the boot.
