The Alpinestars Supertech R Boots are high-performance motorcycle riding boots designed for riders who demand advanced protection, flexibility, and precise control. This black, white, and red model is sized for US 9 / EU 43 and features an advanced microfiber upper for lightweight abrasion resistance and natural movement. The Alpinestars Multi-Link Control system provides external ankle support while helping limit hyper-torsion, hyper-extension, and hyper-flexion. It also contributes to Achilles impact protection during demanding riding conditions.
Protection is supported by a contoured high-modulus shin plate, a wide heel counter, replaceable heel sliders, an external side heel slider, and a dual-density TPU replaceable toe slider with screw-in assembly. Strategically positioned ventilation zones in the heel and shin promote airflow, while flexible accordion microfiber panels at the Achilles, forefoot, and rear boot areas improve mobility. The outside stretch panel allows easier entry and removal while maintaining a secure, close-fitting profile.
Comfort and fit are enhanced by an anatomical replaceable EVA footbed, shock-absorbing forefoot foam, a breathable ankle and leg lining, and a padded self-molding ankle reinforcement. The Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, and hook-and-loop zip-pull retainer provide a precise and secure fit. A durable textured rubber sole supports consistent grip and rider feedback. Manufactured by Alpinestars, these boots are intended for motorcycle riding and are supplied under vendor part number 2220021-123-43.
