The Alpinestars Supertech R Vented Motorcycle Boots are high-performance riding boots designed for riders who demand advanced protection, precise bike control, and dependable ventilation. This red size US 9.5 / EU 44 model features a microfiber upper with dedicated laser-perforated zones that promote airflow while maintaining flexibility and abrasion resistance. The lightweight rubber compound sole provides secure grip on the foot pegs for confident control during street and track riding.
A separate, internally updated bio-mechanical inner bootie uses 3D mesh construction to provide structure, comfort, and natural foot movement. The boot includes a medial synthetic microfiber panel for improved abrasion resistance and enhanced contact feel with the motorcycle. Protection is reinforced with a TPU shifter, redesigned TPU shin plate, soft TPU toe reinforcement, additional ankle padding, and a microfiber top gaiter with TPU over-injection for secure contact and support.
The Alpinestars Supertech R Vented Boots use replaceable co-injected TPU and aluminum toe sliders, a replaceable heel plate slider, and a replaceable shin slider to help manage abrasion during a slide and simplify serviceability. A front flex area supports natural front-to-back movement while improving impact and abrasion protection, and the redesigned rear stretch-microfiber bellow further enhances mobility. Entry and exit are simplified by a TPU stretch panel with zipper, while hook-and-loop retention keeps the zipper puller secure. A micro-adjustable ratchet closure at the top of the boot allows riders to fine-tune the fit.
