Alpinestars Tech 5 boots combine a durable, lightweight microfiber chassis with multi-material construction for motocross and off-road riding. The abrasion-resistant microfiber upper provides water resistance, long-term durability, weight savings, and a consistent fit that is easy to maintain and clean. Synthetic polymer reinforces the toe box for added protection.
A medial-facing biomechanical pivot system connects the lower and upper boot sections to provide front and rear flexibility, support, and stability. Extended accordion flex zones and ergonomically profiled TPU buckle straps promote front flexion, while inward-facing polymer panels feature grip sculpture patterning for improved contact with the bike and enhanced abrasion resistance.
The one-piece TPU-injected dual-compound foot shell delivers impact and abrasion resistance and is reinforced with an internal metal shank and co-injected hard-compound toe reinforcement. Soft poly-foam around the ankles and collar helps absorb shocks, while the full textile interior lining supports rider comfort.
The Alpinestars buckle closure system uses polymer and fiberglass buckle arms with high-impact aluminum bridge closures. Memory and quick-release locking functions, a self-aligning design, and replaceable buckles provide precise closure, durability, and secure performance.
