The Alpinestars Supertech R Vented Motorcycle Boots are high-performance racing boots designed for riders who demand advanced protection, precise fit, and dependable airflow. Finished in fluorescent yellow and black, this size US 12.5 / EU 48 boot uses a microfiber main upper with dedicated laser-perforated zones to promote ventilation while maintaining flexibility and abrasion resistance. The lightweight rubber sole provides reliable grip on the foot pegs, helping improve control during aggressive street or track riding.
The Supertech R Vented boot features a separate, internally updated bio-mechanical inner bootie constructed from 3D mesh for enhanced structure, rider comfort, ankle stability, and natural foot movement. A TPU shin plate, replaceable shin slider, heel plate slider, and co-injected TPU/aluminum toe slider help protect key impact and abrasion zones. The medial side includes a synthetic microfiber panel and TPU shifter reinforcement for added durability and improved contact with the motorcycle.
A TPU stretch panel with a zipper allows easier entry and exit while supporting a closer, more optimized fit. Hook-and-loop closure keeps the zipper pull secured, while the micro-adjustable ratchet closure at the top of the boot enables precise fit adjustment. Additional features include soft TPU toe reinforcement, enhanced ankle padding, a redesigned stretch microfiber rear bellow, and a microfiber top gaiter with TPU over-injection for improved support. Front flex areas improve movement, impact abrasion resistance, and airflow. The Alpinestars Supertech R Vented Boots are suitable for motorcycle racing, track days, and performance street riding.
