The Alpinestars Supertech R Vented Motorcycle Boots are engineered for riders who demand advanced protection, precise control, and all-day comfort on the street or track. This black, red, white, and gray pair is sized at US 9 / EU 43 and features a microfiber main upper with dedicated laser-perforated zones for airflow, flexibility, and abrasion resistance. The lightweight rubber compound sole provides dependable grip on the foot pegs, while the redesigned front flex area and stretch microfiber rear bellow support natural foot movement without compromising protection.
A separate, internally updated bio-mechanical inner bootie uses 3D mesh construction to improve structure, comfort, and stability. The inner bootie includes a soft TPU-reinforced toe area for impact protection and additional ankle padding for support during movement. TPU protection is integrated throughout the boot, including the shin plate, medial shifter panel, top gaiter, and stretch panel. The zippered TPU stretch panel helps simplify entry and exit while delivering a closer, more optimized fit, and the hook-and-loop closure keeps the zipper pull secured in position.
Replaceable co-injected TPU and aluminum toe sliders use an easy screw system to help protect the toe area from abrasion. A replaceable heel plate slider improves sliding performance and protection during a crash, while the replaceable shin slider adds abrasion resistance in a high-impact area. The micro-adjustable ratchet closure at the top of the boot allows riders to fine-tune the fit. The redesigned TPU shin plate enhances impact absorption, and the ventilated flex areas increase airflow for improved breathability. Manufacturer and vendor part number: 2220121-1329-43.
