The ALPINESTARS Tech 5 Boots in Blue/White combine abrasion-resistant microfiber construction with synthetic polymer and advanced protective components for riding support, durability, and controlled flexibility. The upper provides water resistance, reduced weight, and a consistent fit, while the redesigned instep and Achilles accordion flex zones support comfort and control. A contoured polymer core structure surrounds the upper boot for structural integrity and abrasion resistance.
Protection features include an anatomically profiled polymer shin plate with a Velcro adjustable panel, a medial-facing biomechanical pivot system, polymer grip panels for contact with the bike, and a thermoplastic rubber gaiter over the thermoplastic polyurethane calf protector. The buckle closure system uses polymer and fiberglass buckle arms with high-impact aluminum bridge closures, memory and quick-release locking functions, and a self-aligning design. Replaceable buckles and ergonomically shaped TPU buckle straps support convenient use and front flexion.
The one-piece TPU injected dual-compound foot shell includes a metal shank and co-injected toe reinforcement for impact and abrasion resistance. A replaceable dual-compound sole is integrated with the multi-density foot base structure to provide durability, grip, and riding feel. TPU heel and side components add support, while soft poly-foam around the ankles and collar, a full textile interior lining, and a replaceable anatomic EVA footbed contribute to comfort. This Blue/White pair is sized US 11 / EU 45.5 and carries manufacturer and vendor part number 2015015-72-11.
