The Alpinestars Tech 5 motocross boot combines a durable, lightweight microfiber chassis with a multi-material, multi-panel construction designed for off-road performance, comfort, and long-term use. Its abrasion-resistant microfiber upper provides water resistance while helping reduce weight, and the material is easy to maintain and clean.
A medial-facing biomechanical pivot system connects the lower and upper boot sections to provide front and rear flexibility with structural support. Polymer panels with grip sculpture patterning improve contact with the bike and abrasion resistance, while extended accordion flex zones support mobility. The one-piece TPU-injected dual-compound foot shell offers impact and abrasion resistance, with an internal metal shank and co-injected toe reinforcement.
Soft poly-foam around the ankles and collar provides shock-absorbing performance, and the interior textile lining adds comfort. The 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 support precise closure and convenient use. The ergonomically profiled TPU buckle straps promote front flexion. These red, white, and black Alpinestars boots are size 11 and feature part number 2015015-321-11.
