The Alpinestars Youth Tech 3S Motorcycle Boots are designed for junior riders with smaller feet who need dependable protection, comfort, and control while riding off-road motorcycles, dirt bikes, and ATVs. This youth-specific boot features a flexible microfiber upper that supports natural movement while providing durability and abrasion resistance. The US 4 size is designed to fit junior riders and corresponds to approximately EU 37 sizing.
Protection is provided by an external polyurethane shin guard, an injected thermoplastic polyurethane shin plate, and a TPU medial protector panel. Internal ankle protection is molded into the boot construction, while the one-piece dual-compound TPU foot shell is reinforced with a metal shank and co-injected toe reinforcement. An external PU toe protector improves grip and helps shield the foot from impacts and abrasion. The hook-and-loop upper closure, TPR calf flap, and adjustable design help provide a secure fit across a range of calf sizes.
The Tech 3S includes a three-stage instep flex zone for improved comfort, support, and control. Its exclusive rubber outsole uses a side-wrapping design for reliable traction and durability against the foot controls. A suede calf panel helps maintain grip against the motorcycle, and the replaceable anatomical EVA footbed supports long-term comfort. Select youth sizes from US 10 through US 4 also include an adapted removable footbed designed to accommodate growth and extend product usability. Manufactured by Alpinestars, this boot is a purpose-built fitment for youth riders seeking versatile off-road riding protection.
