The Alpinestars Supertech R motorcycle boots deliver advanced protection, flexibility, and control for demanding street and track riding. Featuring an advanced microfiber upper, these black and white riding boots provide lightweight performance with excellent abrasion resistance and a comfortable, precise fit. The US 8 / EU 42 size is designed for riders seeking a supportive boot with responsive pedal feel and natural movement.
Protection: The contoured high-modulus shin plate helps protect against impact and abrasion, while Alpinestars’ evolved Multi-Link Control system supports ankle articulation and helps limit hyper-torsion, hyper-extension, and hyper-flexion. The system also provides Achilles impact protection. A dual-density TPU replaceable toe slider, replaceable heel slider, external side heel slider, wide heel counter, shock-absorbing padded insert, and self-molding ankle reinforcement provide additional coverage in key impact areas.
Comfort and Mobility: Soft microfiber flex zones, accordion panels at the Achilles and forefoot, and strategically placed ventilation areas promote airflow and natural forward, backward, and lateral movement. The advanced synthetic forefoot lining uses open-cell foam for shock absorption, while breathable ankle and leg lining materials improve comfort during extended rides. The anatomical, replaceable EVA footbed provides arch support and enhanced forefoot pedal feedback.
Closure and Fit: The Alpinestars Lace-Lock System uses an advanced polymer resin for secure, precise closure. Inner instep speed lacing, a lateral zipper, stretchable entry panel, micro-adjustable ratchet top closure, and hook-and-loop zip-pull retention help create a close, secure fit. The durable rubber sole provides consistent grip and riding feel.
