The Alpinestars Supertech R motorcycle boots are engineered for high-performance sport riding, track use, and demanding street applications. This red US 7.5 / EU 41 model combines an advanced microfiber upper with strategically placed stretch and accordion panels to provide a close, supportive fit while maintaining natural forward, backward, and lateral movement. The manufacturer part number and vendor part number are both 2220021-3029-41.
Protection is built into the boot with a contoured high-modulus shin plate, external ankle support, replaceable toe and heel sliders, and a wide heel counter with shock-absorbing padding. Alpinestars Multi-Link Control system helps limit hyper-torsion, hyper-extension, and hyper-flexion while supporting ankle articulation and providing Achilles impact protection. A dual-density TPU toe slider and external side heel slider help promote controlled sliding and dissipate impact energy during an incident.
Feature: Breathable TPU construction and strategically positioned ventilation in the heel and shin improve airflow during extended rides. Feature: Flexible accordion microfiber zones at the Achilles, front, and rear enhance mobility without sacrificing support. Feature: Alpinestars Lace-Lock System, inner instep speed lacing, and a lateral zipper provide a precise, secure closure. Feature: The micro-adjustable ratchet top closure and hook-and-loop tab keep the zipper pull secured and flat. Feature: An anatomical, replaceable EVA footbed provides arch support and pedal feel, while the durable textured rubber sole delivers consistent grip. The advanced synthetic forefoot lining with open-cell foam adds shock absorption, and breathable ankle and leg linings improve comfort. These boots are designed to fit riders seeking race-inspired protection and responsive control in the specified US 7.5 / EU 41 size.
