This black model is sized US 12.5 \/ EU 48 and features a race-derived construction that balances protection, flexibility, and rider control. The advanced microfiber upper provides lightweight abrasion resistance while maintaining the mobility needed for aggressive riding positions and everyday walking.\u003c\/p\u003e\u003cp\u003eProtection is built into the boot through Alpinestars' unique ankle brace system, which supports the connection between the lower calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. Dual-density TPU ankle protectors, a race-derived TPU shin plate, and integrated Achilles and ankle impact protection help shield key areas during a crash. Front and rear flex zones use textile over-injected with soft TPU to improve impact and abrasion resistance without restricting natural forward and backward movement.\u003c\/p\u003e\u003cp\u003eThe SMX-6 V3 includes Alpinestars' Lace-Lock System, made from advanced polymer resin for fast, precise, and secure closure. A TPU shifter zone protects the lower medial side of the boot, while replaceable dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider provide additional coverage and support controlled sliding during an incident. These features also help preserve walking flexibility between riding sessions.\u003c\/p\u003e\u003cp\u003eManufacturer: Alpinestars. Vendor part number: 2223025-10-48.
