Alpinestars SMX-6 V3 Boots — EU 47, Black

Designed as the ultimate track and performance riding all-rounder, the SMX-6 V3 combines race-derived materials and engineering to give riders an edge on both track and street 🏁.

The advanced microfiber upper delivers lightweight abrasion resistance and excellent flexibility. Front flex and back flexion zones are constructed with textile over-injected with a soft thermoplastic polyurethane (TPU) to enhance impact abrasion protection while promoting natural forward and backward movement.

A unique ankle brace protection system provides biomechanical support between the lateral top calf, shin, and ankle, limiting hyper-torsion, hyper-extension, and hyper-flexion, while offering Achilles and ankle impact protection. The lace-lock system uses an advanced polymer resin for a quick, precise, and secure closure.

Additional protective elements include a TPU shifter zone on the lower medial side, a race-derived TPU shin plate, dual-density TPU ankle protectors positioned between the upper and lining, and replaceable dual-density TPU toe and heel sliders with screw-in assemblies for comprehensive protection and optimized sliding performance.

Materials: 37% TPU, 35% microfiber, 11% polyester, 8% polyurethane, 8% TPR, 1% elastic. Inner lining: 82% polyester, 18% synthetic.
