The Alpinestars Supertech R motorcycle boots are designed for high-performance street and track riding, combining advanced protection, flexibility, airflow, and precise fit. This red size US 6.5 / EU 40 model uses an advanced microfiber upper for lightweight durability and excellent abrasion resistance. The front flex area and Achilles zone incorporate flexible microfiber accordion panels to support natural forward-and-back movement, while strategically positioned ventilation areas in the heel and shin help promote airflow during demanding rides.
Protection is provided by a contoured high-modulus shin plate, replaceable toe and heel sliders, and a wide heel counter with lateral ventilation. Alpinestars’ Multi-Link Control system helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while adding Achilles impact protection. Shock-absorbing inserts, self-molding ankle reinforcement, and a dual-density TPU replaceable toe slider provide additional coverage in key impact areas. The outer side heel slider is designed to help absorb impact and promote controlled sliding during an accident.
Inside, the boots feature a breathable ankle and leg lining, open-cell foam cushioning, and an anatomical replaceable EVA footbed that supports the arch and enhances pedal feel. The durable rubber sole provides consistent grip and a connected riding feel. Alpinestars’ Lace-Lock System, inner instep speed-lacing closure, lateral zipper, and hook-and-loop zip-pull retainer deliver a secure, adjustable fit and streamlined entry and removal. Manufactured by Alpinestars and supplied under vendor part number 2220021-3029-40, these boots are designed to fit riders seeking race-inspired protection for motorcycle street and track applications.
