The Alpinestars Supertech R Boots deliver advanced protection, flexibility, and precise fit for performance-focused motorcycle riding. Finished in black, magenta, white, and yellow, these boots are sized for US 12.5 / EU 48 and feature an advanced microfiber upper for lightweight performance, abrasion resistance, and natural movement. The front flex area, large asymmetrical accordion zones, and flexible Achilles panel support comfortable forward and backward articulation while maintaining protective coverage.
The boots use Alpinestars Multi-Link Control System technology to help limit hyper-torsion, hyper-extension, and hyper-flexion of the ankle 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 protect key impact areas and promote controlled sliding during an accident. The wide heel counter includes lateral ventilation, a shock-absorbing padded insert, and self-molding ankle reinforcement for added support and comfort.
A breathable construction combines strategically positioned ventilation in the heel and shin with open-cell foam laminated lining in the forefoot and highly breathable materials through the ankle and leg areas. The Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, and hook-and-loop zip-pull tab provide a secure, adjustable fit. A micro-adjustable ratchet top closure helps seal the upper, while the anatomical replaceable EVA footbed supports the arch and enhances pedal feel. The durable rubber sole provides consistent grip through an evenly textured surface. The manufacturer part number and vendor part number are 2220021-1634-48.
