The Alpinestars Supertech R Vented Motorcycle Boots are designed for riders who demand advanced protection, precise fit, and reliable control on the road or track. This black, red, white, and gray model is sized at US 11.5 / EU 46 and features a microfiber main upper with dedicated laser-perforated zones for airflow, flexibility, and abrasion resistance. The lightweight rubber sole provides dependable grip on the foot pegs, while the synthetic microfiber medial panel improves abrasion resistance and rider feedback when contacting the motorcycle.
A separate, internally updated biomechanical inner bootie uses 3D mesh material to provide structure, comfort, and natural foot movement. The bootie includes a soft TPU toe reinforcement and additional ankle padding for impact protection and stability. A TPU shin plate improves impact absorption, while a replaceable shin slider adds abrasion resistance in a high-contact area. The replaceable co-injected TPU and aluminum toe slider uses an easy screw system to help protect the toe area, and the replaceable heel plate slider is designed to promote smooth sliding during a crash.
Fitment is optimized through a TPU stretch panel with zipper entry, a hook-and-loop closure that keeps the zipper puller secure, and a micro-adjustable ratchet closure at the top of the boot. The redesigned rear stretch-microfiber bellow supports natural front-to-back movement, while the front flex area improves mobility, impact abrasion protection, ventilation, and airflow. A microfiber top gaiter with TPU over-injection helps provide a secure interface with riding gear. Manufactured by Alpinestars and identified by vendor part number 2220121-1329-46, these boots are suited for performance-oriented motorcycle riding and track-focused applications.
