Alpinestars SMX-6 V3
The sweet-spot sport-touring boot: a CE-certified (EN 13634) microfiber boot with a TPU ankle brace, race-derived shin plate and dual-density ankle protectors, but with front-flex and back-flexion zones that keep it walkable off the bike. Real protection without race-boot stiffness.
Strengths
- TPU lateral ankle brace, dual-density ankle protectors and a race-derived shin plate
- Front-flex and back-flexion zones give natural articulation and walkability
- Replaceable dual-density TPU toe sliders; CE certified to EN 13634:2017
Trade-offs
- Standard/vented version is not waterproof (separate Drystar and Gore-Tex variants are)
- Microfiber upper, not full leather
