The Alpinestars Supertech R motorcycle boots deliver advanced protection, flexibility, and riding control for performance-focused street and track riders. This Black/White/Red model is sized US 9.5 / EU 44 and features an advanced microfiber upper that helps reduce weight while providing excellent abrasion resistance and natural forward-and-backward movement. Thermoplastic polyurethane (TPU) components support airflow and breathability, while strategically positioned ventilation areas in the heel and shin help improve comfort during demanding rides.
Protection is built into the boot through a contoured high-modulus shin plate, wide heel counter, shock-absorbing padded insert, self-molding ankle reinforcement, and replaceable heel and external side heel sliders. Alpinestars’ Multi-Link Control system helps limit hyper-torsion, hyper-extension, and hyper-flexion of the ankle while adding Achilles impact protection. A dual-density TPU replaceable toe slider provides coverage around the outer toe area, and large asymmetrical accordion zones improve flexibility. The flexible Achilles panel and stretchable outside entry panel support a close, comfortable fit while making the boots easier to put on and remove.
The Supertech R includes an advanced synthetic forefoot lining with open-cell foam for shock absorption, plus breathable lining through the ankle and leg areas. An anatomical, replaceable contoured EVA footbed provides arch support and improved pedal feel, while the durable textured rubber sole delivers consistent grip. The Alpinestars Lace-Lock System, inner instep speed-lacing closure, lateral zipper, and hook-and-loop zip-pull tab work together for a precise, secure fit. This product is manufactured by Alpinestars and is identified by manufacturer and vendor part number 2220021-123-44.
