The Alpinestars Tech 5 motorcycle boots are designed for riders who need dependable protection, controlled flexibility, and long-term comfort. This size US 9 boot, equivalent to EU 43, features an abrasion-resistant microfiber upper with synthetic polymer reinforcement at the toe box. The main microfiber construction provides water resistance, durability, reduced weight, and easy maintenance for consistent performance over extended use.
A contoured polymer core surrounds the upper boot for structural integrity and abrasion resistance while allowing controlled flex. The anatomically shaped polymer shin plate provides impact protection and includes a hook-and-loop adjustable panel for a personalized, secure fit. Redesigned microfiber accordion zones at the instep and Achilles support comfortable movement, while the medial biomechanical pivot system connects the upper and lower boot sections for front-to-rear flexibility and structural support. Grip-patterned polymer panels improve contact with the motorcycle and add abrasion resistance.
The Alpinestars Tech 5 boot uses a replaceable buckle system with polymer and fiberglass arms, high-impact aluminum bridge closures, memory retention, quick release, and self-aligning operation. Ergonomic TPU straps promote forward flexion, and the buckles are replaceable for convenient service. A dual-compound injected TPU foot shell includes a metal shank and reinforced toe for enhanced impact and abrasion resistance. The replaceable sole is integrated with a multi-density foot base for durability, grip, riding feel, and support. A TPU heel patch, rear TPR gaiter, soft ankle and collar padding, full textile lining, and a replaceable anatomic EVA footbed complete the protective fit.
Finished in Orange Fluorescent, Blue, and Yellow Fluorescent, this Alpinestars boot is intended for motorcycle riding applications where reliable lower-leg, ankle, and foot protection are essential.
