The Alpinestars Supertech R motorcycle racing boots are designed for riders who demand advanced protection, precise fit, and responsive control on the track or street. This red pair is sized for US 9.5 / EU 44 and features an advanced microfiber upper that combines lightweight performance with flexibility and abrasion resistance. The front flex area and large asymmetric accordion zones support natural forward and backward movement, while flexible microfiber around the Achilles enhances mobility.
Protection is provided by a contoured high-modulus shin plate, replaceable toe and heel sliders, and a wide heel counter with lateral ventilation. Alpinestars’ Multi-Link Control system helps limit hyper-torsion, hyper-extension, and hyper-flexion of the ankle while adding Achilles impact protection. The boot also includes external side heel protection designed to help absorb and dissipate impact forces during a slide. Strategically positioned ventilation areas in the heel and shin promote airflow during demanding rides.
A secure, adjustable fit comes from the Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, stretch accordion entry panel, and hook-and-loop tab that keeps the zipper pull secured. The micro-adjustable ratchet top closure helps provide a close fit around the upper boot. Inside, the breathable ankle and leg lining, open-cell foam forefoot lining, and replaceable contoured EVA footbed provide comfort, arch support, shock absorption, and a connected pedal feel. A durable textured rubber sole supplies consistent grip and riding feedback.
Manufactured by Alpinestars and supplied under the vendor part number 2220021-3029-44, these Supertech R boots are intended for motorcycle riders seeking race-focused ankle, shin, heel, and toe protection with a precise, performance-oriented fit.
