The Alpinestars SMX-6 V3 Motorcycle Boots are race-derived performance boots designed for riders who demand dependable protection, flexibility, and control on the street or track. This black pair is sized US 7.5 / EU 41 and is manufactured by Alpinestars under model SMX-6 V3. The vendor part number and manufacturer part number are 2223025-10-41.
Feature: Advanced microfiber upper construction delivers lightweight abrasion resistance, high-performance protection, and flexible movement. Front and rear flexion zones combine textile with soft thermoplastic polyurethane (TPU) reinforcement to improve impact and abrasion protection while supporting natural forward and backward motion. Alpinestars’ ankle brace protection system provides biomechanical support between the calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while protecting the Achilles area and ankle from impacts.
Feature: The Alpinestars Lace-Lock System uses an advanced polymer resin closure for quick, precise, and secure fastening. A TPU shifter zone reinforces the lower medial area, while the race-derived TPU shin plate and dual-density TPU ankle protectors provide targeted impact and abrasion protection. Replaceable dual-density TPU toe sliders use a screw-in assembly for coverage around the outer toe area without restricting walking comfort. Replaceable heel and external side heel sliders help dissipate and absorb shock while encouraging controlled sliding during an accident.
Designed for sport riding, track use, and performance-focused street applications, the Alpinestars SMX-6 V3 offers protective coverage with articulation suited to active motorcycle riding. The US 7.5 / EU 41 fit makes this model appropriate for riders seeking a performance boot in this specific size. Always verify the sizing chart and intended riding application before purchase.
