The Alpinestars Supertech R Vented Motorcycle Boots are designed for sport and track riders seeking advanced protection, airflow, and precise foot control. This black US 9 / EU 43 model uses a microfiber upper with dedicated laser-perforated zones to promote ventilation while maintaining flexibility and abrasion resistance. The boot is built around a separate, updated bio-mechanical inner bootie made from 3D mesh material, providing structure, rider comfort, ankle support, and natural foot movement.
Protection is supplied by a redesigned TPU shin plate, replaceable shin slider, TPU shifter, reinforced toe area, and additional ankle padding. Replaceable co-injected TPU and aluminum toe sliders use an easy screw system to help protect the toe against abrasion, while the replaceable heel plate slider supports controlled movement and protection during a crash. A lightweight rubber compound sole delivers dependable grip on the foot pegs, and the synthetic microfiber medial panel improves abrasion resistance and contact with the motorcycle.
The Supertech R Vented Boots feature a TPU stretch panel with a zipper for easier entry and exit, along with a hook-and-loop closure that keeps the zipper pull secured during riding. A micro-adjustable ratchet closure at the top helps provide a close, optimized fit. The front flex area supports natural forward and backward movement while improving impact abrasion resistance and airflow. A redesigned stretch microfiber rear bellow and microfiber top gaiter with TPU over-injection further enhance mobility, fit, and grip. Alpinestars manufacturer and vendor part number 2220121-10-43 identifies this specific black US 9 / EU 43 configuration.
