The Alpinestars Supertech R Motorcycle Boots in Black/White/Red are engineered for high-performance sport and track riding. This size US 12.5 / EU 48 model features an advanced microfiber upper that combines lightweight construction, flexibility, and abrasion resistance. The Alpinestars Supertech R provides a close, secure fit with stretch accordion panels at the entry and exit area, large front and rear flex zones, and a flexible Achilles section designed to support natural forward and backward movement.
Protection is built around Alpinestars’ Multi-Link Control system, which helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while providing Achilles impact protection. A contoured high-modulus shin plate, dual-density TPU replaceable toe slider, replaceable heel slider, and external side heel slider help manage impact and abrasion during a slide. Ventilation zones in the heel and shin promote airflow, while the wide heel counter, padded shock-absorbing insert, and self-molding ankle reinforcement add support and comfort.
The Alpinestars Lace-Lock System uses an advanced polymer resin closure for quick, precise adjustment, supported by an inner instep speed-lacing closure and lateral zipper. A hook-and-loop tab secures the zipper pull in a flat position. Inside, the advanced synthetic forefoot lining uses open-cell foam for shock absorption, while breathable ankle and leg lining improves comfort. The anatomical, replaceable contoured EVA footbed supports the arch and helps maintain pedal feel. A durable textured rubber sole provides consistent grip and riding feedback.
