The Alpinestars Youth Tech 3S Motorcycle Boots are designed specifically for junior riders with smaller feet who need dependable protection, comfort, and control on the bike. This black and white boot is sized for US 4 and EU 37 and features a rider-focused construction that supports developing skills across a broad range of riding conditions. The lightweight microfiber upper provides flexibility, durability, and abrasion resistance, while the three-stage instep flex zone promotes natural movement without sacrificing support.
Protection is built into the boot through an injected thermoplastic polyurethane (TPU) shin plate connected to the TPU medial protector panel, along with an external polyurethane (PU) shin guard for impact and abrasion resistance. Internal ankle protection is molded into the boot’s construction, and the one-piece, dual-compound TPU foot shell is reinforced with a metal shank and co-injected toe reinforcement. An external PU toe protector enhances grip and safety, while the hook-and-loop upper closure and thermoplastic rubber flap allow broad calf-fit adjustment.
The exclusive rubber outsole uses a side-wrapping design for added coverage and traction, while an external suede calf panel helps provide grip against the motorcycle. A replaceable anatomical EVA footbed supports long-term comfort and serviceability. Selected youth sizes from US 10 through US 4 include a specially adapted removable footbed designed to accommodate growth and extend product longevity. The Alpinestars Youth Tech 3S is a purpose-built junior motocross and off-road boot that combines flexible fit, durable materials, and integrated lower-leg and foot protection.
