The Alpinestars Tech 5 motocross boot combines a durable, lightweight microfiber chassis with advanced support, flexibility and comfort for motocross and off-road riding. Its abrasion-resistant microfiber upper provides water resistance, long-term durability and a consistent fit, while the synthetic polymer toe box adds reinforcement in a high-wear area.
A medial-facing biomechanical pivot system links the lower and upper boot sections to provide front and rear flexibility with structural support. Extended accordion flex zones and ergonomically profiled TPU buckle straps promote front flexion, while polymer panels with grip sculpture patterning improve contact with the bike and abrasion resistance.
The one-piece TPU-injected dual-compound foot shell delivers impact and abrasion resistance and includes a metal shank and co-injected toe reinforcement. Soft poly-foam around the ankles and collar helps absorb shock, and a full textile interior lining enhances comfort. The buckle closure system uses polymer and fiberglass buckle arms with high-impact aluminum bridge closures. Memory functionality, quick-release locking, self-aligning design and replaceable buckles support precise closure and secure riding performance.
Finished in red, white and black, the Alpinestars Tech 5 is identified by part number 2015015-321-13 and is offered in size 13.
