Alpinestars SMX-6 V3 Boots — EU 45, Black/Red

The SMX-6 V3 is packed with innovative safety and protective features, built as a track and performance riding all‑rounder that delivers a critical performance edge on both track and street.

Advanced microfiber upper construction provides lightweight, high-performance protection against abrasion while maintaining superb flexibility for aggressive riding.

Front flex and back flexion zones are constructed with textile over‑injected with a soft TPU for enhanced impact abrasion resistance and natural forward/back movement.

A unique ankle brace protection system provides bio‑mechanical support between the lateral top calf, the shin and the ankle, limiting hyper‑torsion, hyper‑extension and hyper‑flexion while adding Achilles and ankle impact protection.

The integrated Lace‑Lock System uses advanced polymer resin for a quick, precise and secure closure, and a TPU shifter zone protects the lower medial side.

Race‑derived TPU shin plate and dual density TPU ankle protectors deliver strategic impact and abrasion resistance in key contact areas.

Replaceable dual density TPU toe sliders (screw‑in) and external heel/side heel sliders are positioned for optimum shock dissipation and sliding performance, while preserving walking flexibility and comfort.
