The Alpinestars Tech 5 is an advanced multi-material, multi-panel motocross and off-road boot designed for support, comfort, durability, and riding performance. Its innovative microfiber chassis is lightweight, abrasion-resistant, water-resistant, durable, and easy to maintain, while the construction helps provide a consistent fit during long-term use.
A medial-facing biomechanical pivot system connects the upper and lower sections of the boot to support front and rear flexibility and structural stability. Extended accordion flex zones and ergonomically profiled TPU buckle straps promote front flexion. Polymer panels with grip sculpture patterning provide contact with the bike and added abrasion resistance.
The one-piece TPU-injected dual-compound foot shell offers impact and abrasion resistance and is reinforced with an internal metal shank and co-injected toe reinforcement. Soft poly-foam around the ankles and collar provides shock-absorbing performance, while the full textile interior lining supports comfort.
The Alpinestars buckle closure system uses polymer and fiberglass buckle arms with high-impact aluminum bridge closures for durability and reduced weight. Memory and quick-release locking functions, a self-aligning design, and replaceable buckles support precise closure and security. This white and black Tech 5 boot is size 12 and has part number 2015015-21-12.
