The Alpinestars Supertech R Motorcycle Boots are designed for high-performance sport riding and track use, combining advanced protection, flexibility, and precise fit. This red model is sized for US 12 / EU 47 and features an advanced microfiber upper that helps reduce weight while providing excellent abrasion resistance and natural movement. The front flex area, Achilles section, and large asymmetrical accordion zones support forward, backward, and lateral flexibility without compromising rider protection.
Protection is provided by a contoured high-modulus shin plate, reinforced ankle construction, and Alpinestars’ Multi-Link Control System. This external support system helps limit excessive ankle hyper-torsion, hyper-extension, and hyper-flexion while providing Achilles impact protection. Replaceable dual-density TPU toe sliders, heel sliders, and an external side heel slider help protect key contact areas and promote controlled sliding during an accident. Strategically positioned ventilation zones in the heel and shin support airflow during demanding rides.
The Supertech R includes the Alpinestars Lace-Lock System, an inner instep speed-lacing closure, and a lateral zipper for a secure, adjustable fit. The micro-adjustable ratchet top closure stows the strap end, while a hook-and-loop tab keeps the zipper pull secured and flat. An anatomical, replaceable EVA footbed provides arch support and pedal feedback, and the durable rubber sole delivers consistent grip. The advanced synthetic forefoot lining includes open-cell foam for shock absorption, while breathable lining through the ankle and leg areas improves comfort. Manufactured by Alpinestars and supplied under vendor part number 2220021-3029-47, these boots are intended for riders seeking track-focused protection, mobility, and dependable control.
