This black, silver, and red model is sized at US 11.5\/EU 46 and features an advanced microfiber upper that balances lightweight construction, abrasion resistance, flexibility, and riding comfort. Manufacturer part number and vendor part number: 2223025-199-46.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProtection and fitment:\u003c\/strong\u003e The boots are intended to fit motorcycle riders seeking reinforced coverage around the foot, ankle, shin, heel, and toe areas. Front and rear flex zones combine textile construction with soft TPU over-injection to support natural forward and backward movement while improving impact and abrasion resistance. 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.\u003c\/p\u003e\u003cp\u003eThe Alpinestars Lace-Lock System uses an advanced polymer resin closure for fast, secure, and precise adjustment. A TPU shifter zone protects the lower medial side of the boot, while a race-derived TPU shin plate and dual-density TPU ankle protectors reinforce key impact areas. The replaceable dual-density TPU toe slider uses a screw-in design for protective coverage around the outer toe, and replaceable heel and external side heel sliders are positioned to help dissipate impact energy and promote controlled sliding during an accident. The SMX-6 V3 combines protective motorcycle-specific fitment with the mobility needed for walking and active riding.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdvanced microfiber upper: Provides lightweight abrasion resistance, flexibility, and high-performance motorcycle protection.\u003c\/li\u003e\n\u003cli\u003eFlex protection zones: Textile and soft TPU construction supports natural forward and backward movement while enhancing impact and abrasion resistance.\u003c\/li\u003e\n\u003cli\u003eAnkle brace protection system: Helps support ankle articulation while limiting hyper-torsion, hyper-extension, and hyper-flexion.\u003c\/li\u003e\n\u003cli\u003eLace-Lock System: Advanced polymer resin closure provides quick, precise, and secure fastening.\u003c\/li\u003e\n\u003cli\u003eTPU shin and ankle protection: Reinforces key impact areas between the outer upper and padded lining.\u003c\/li\u003e\n\u003cli\u003eReplaceable toe slider: Dual-density TPU screw-in slider protects the outer toe while preserving walking flexibility.\u003c\/li\u003e\n\u003cli\u003eReplaceable heel sliders: Strategic heel protection helps dissipate impact energy and promote controlled sliding.\u003c\/li\u003e\n\u003cli\u003eSport riding fitment: Designed for motorcycle track, performance, and street riding in US 11.5\/EU 46.\u003c\/li\u003e\n\u003cli\u003eBrand: Alpinestars.\u003c\/li\u003e\n\u003cli\u003eModel: SMX-6 V3.\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 2223025-199-46.\u003c\/li\u003e\n\u003cli\u003eVendor part number: 2223025-199-46.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":67565276659947,"sku":"34041829","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/4368833.png?v=1790785371","url":"https:\/\/ctracingservices.com\/products\/alpinestars-smx-6-v3-motorcycle-boots-black-silver-red-us-11-5-eu-46-part-2223025-199-46","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
