Alpinestars Tech 5 Boots — US Size 9, Over-Calf, Black

The Tech 5 boots combine advanced materials and a reinforced shell to deliver exceptional protection, fit and control. The abrasion-resistant microfiber upper and synthetic polymer toe box provide durable water resistance, long-term consistent fit and easy maintenance. 🔒

Contoured polymer core structure and an anatomically profiled, high-modulus shin plate offer superior impact and abrasion resistance while allowing controlled flex. Redesigned instep and Achilles accordion flex zones enhance comfort and rider control. A medial-facing biomechanical pivot system links upper and lower sections for natural movement and structural support.

The one-piece injected dual-compound TPU foot shell features internal metal shank reinforcement and co-injected toe reinforcement for unmatched impact protection. An exclusive dual-compound sole integrates with a multi-density foot base for built-in support, superior grip and replaceable durability. Buckle closures use polymer and fiberglass arms with high-impact aluminum bridges, offering memory, quick-release locking and easily replaceable components. 🛠️

Comfort features include soft poly-foam around the ankles, full interior textile lining and a replaceable anatomic EVA footbed. Designed for demanding off-road use, these boots balance protection, performance and long-term fit stability.
