The Alpinestars Tech 5 motorcycle boots are designed for riders who need dependable protection, controlled flexibility, and all-day comfort. This blue and white boot is sized for US 9 / EU 43 and features a durable microfiber upper with synthetic polymer reinforcement across the toe box. The abrasion-resistant microfiber construction provides water resistance, reduces weight, and is easy to clean while maintaining a consistent fit through extended use. Alpinestars manufactures the Tech 5 for demanding off-road and motocross applications where impact protection and bike control are essential.
Protection comes from a contoured polymer core structure, an anatomically profiled shin plate, and a reinforced one-piece TPU injected dual-compound foot shell. The shin plate is designed for impact and abrasion resistance and includes a hook-and-loop adjustable panel for a secure, personalized fit. A medial-facing biomechanical pivot system connects the upper and lower boot sections to support front and rear flex while maintaining structural integrity. Grip-patterned polymer panels on the inward-facing surfaces improve contact with the motorcycle and add abrasion resistance, while a TPR gaiter and TPU calf protector help shield the rear of the lower leg.
The Tech 5 uses an innovative buckle closure system with polymer and fiberglass arms, high-impact aluminum bridge closures, memory retention, quick-release locking, and self-aligning operation. Replaceable buckles and ergonomically shaped TPU straps simplify maintenance and support natural front flexion. Inside, soft poly-foam around the ankles and collar helps absorb shock, while the textile lining improves comfort. The replaceable anatomic EVA footbed, reinforced metal shank, and integrated dual-compound sole provide support, grip, durability, and riding feel. The sole is replaceable for long-term serviceability. Alpinestars part number 2015015-72-9 identifies this Tech 5 boot configuration.
