The Alpinestars Tech S Youth boots are technical, high-performance motocross/off-road boots for entry-level youth riders. Designed for junior riders, they are made from innovative, lightweight microfibre material that is flexible and abrasion-resistant, with light microfibre on the front and rear bellows for added comfort in the flex areas. The toe box is made of synthetic material for high abrasion resistance. An extended PU synthetic gaiter helps seal out water and dirt, while a contoured TPU calf guard, TPU higher medial guard, TPU outer lateral ankle guard and TPU heel counter provide support and impact resistance. A rear TPU gaiter patch applied on top of the TPU guard gives added impact resistance and comfort on the rear flex zone. The injected TPU shin plate is connected with the TPU medial guard panel, and a hook-and-loop upper boot closure with a TPR flap fits a wide range of calf sizes while providing comfort and support. Ideal for growing kids! The biomechanical medial blade system allows good front/rear flex of the boot and provides support and impact resistance to the ankle, while the ergonomic TPU triple buckle straps wrap smoothly around the front flex area from the medial guard to the lateral side of the boot without compromising boot flex. The techno-polymer secure closure system of a ratchet closure with a memory system and a quick-release/locking system with a self-aligning design gives an easy, precise and secure closure. All the buckles are replaceable. The Tech S boots are ultra-comfortable thanks to an innovative one-piece TPU-injected dual-compound foot shell that is reinforced by a metal shank inside a co-injected toe reinforcement. Soft foam surrounds the ankle and boot collar for comfort and shock-absorbing performance with a textile lining for comfort. The footbed is a replaceable anatomical EVA and is a specially modified smaller footbed to accommodate growth and extended longevity of the product. The high-grip rubber compound sole keeps you sure-footed. Also available in a choice of colours.
