The Alpinestars Supertech R Vented Motorcycle Boots are engineered for riders who demand advanced protection, precise fit, and dependable control on the track or street. This black, fluorescent red, and white model is sized US 7.5 / EU 41 and features a lightweight rubber sole compound that provides excellent grip on the foot pegs. The main upper uses flexible microfiber with dedicated laser-perforated zones to promote airflow while maintaining abrasion resistance and structural support.
Manufacturer fitment is designed for motorcycle riding, with a performance-oriented construction that supports natural foot movement and secure bike contact. A separate internally updated bio-mechanical inner bootie made with 3D mesh provides enhanced structure and rider comfort. The redesigned front flex area improves mobility, impact abrasion resistance, and ventilation, while the stretch microfiber rear bellow supports natural forward and backward movement. A TPU-over-injected microfiber top gaiter improves grip and helps create a secure connection around the lower leg.
Protection features include a TPU shin plate designed for improved impact absorption, a replaceable shin slider, and a TPU shifter panel that reinforces the lower medial side. The inner bootie includes a soft TPU toe reinforcement and additional ankle padding for impact protection and stability. Replaceable co-injected TPU and aluminum toe sliders use an easy screw system, while the replaceable heel plate slider helps improve sliding performance during a crash. A TPU stretch panel with zipper makes entry and exit easier, and the hook-and-loop closure keeps the zipper pull securely in position. The micro-adjustable ratchet closure at the top of the boot allows riders to fine-tune the fit.
These Alpinestars Supertech R Vented Boots are supplied under manufacturer and vendor part number 2220121-124-41. Their combination of ventilated microfiber construction, replaceable sliders, protective TPU components, and adjustable closures makes them a suitable fit for performance-focused motorcycle riders seeking a secure, comfortable boot for track and aggressive street use.
