This black boot features a lightweight microfiber upper reinforced with polymer protection and Alpinestars’ Multi-Link Control (MLC) system. The MLC design helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while preserving natural ankle movement. This model is sized for US 12 \/ EU 47 and is identified by manufacturer and vendor part number 2221119-10-47.\u003c\/p\u003e\u003cp\u003eProtection is supported by a contoured high-modulus shin plate, wide heel counter, molded ankle protectors, and replaceable toe and heel sliders. The dual-density TPU toe slider helps shield the outer toe area, while the heel slider system is designed to help absorb impact and promote controlled sliding during an incident. Microfiber accordion panels at the front, rear, and Achilles provide flexibility for riding movement, while the reinforced front flex area improves abrasion resistance. Ventilation zones in the heel and shin areas encourage airflow for added comfort during warm-weather riding.\u003c\/p\u003e\u003cp\u003eThe SMX Plus V2 uses an inner instep speed-lacing closure, a lateral zipper, and Alpinestars’ Lace-Lock System for a precise, secure fit. A micro-adjustable ratchet top closure helps stabilize the boot around the calf, and a hook-and-loop tab keeps the zipper pull secured. Inside, the advanced synthetic lining uses open-cell foam for shock absorption, while breathable materials support comfort around the ankle and leg. The anatomical, replaceable EVA footbed provides arch support and pedal feel. A durable rubber sole offers consistent grip and riding feedback, making these Alpinestars boots a strong choice for motorcycle street, sport, and track applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: US 12 \/ EU 47\u003c\/li\u003e\n\u003cli\u003eModel: SMX Plus V2 Vented Motorcycle Boots\u003c\/li\u003e\n\u003cli\u003eBrand: Alpinestars\u003c\/li\u003e\n\u003cli\u003eManufacturer and vendor part number: 2221119-10-47\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eAdvanced microfiber upper provides lightweight protection, flexibility, and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eMulti-Link Control system helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion\u003c\/li\u003e\n\u003cli\u003eContoured high-modulus shin plate provides impact and abrasion protection\u003c\/li\u003e\n\u003cli\u003eReplaceable dual-density TPU toe slider with screw-in assembly\u003c\/li\u003e\n\u003cli\u003eReplaceable heel slider and external side heel slider help absorb impact and promote controlled sliding\u003c\/li\u003e\n\u003cli\u003eVentilated heel and shin areas improve airflow\u003c\/li\u003e\n\u003cli\u003eAccordion microfiber panels support natural forward, backward, and Achilles movement\u003c\/li\u003e\n\u003cli\u003eInner speed-lacing closure, lateral zipper, and Lace-Lock System provide a precise fit\u003c\/li\u003e\n\u003cli\u003eMicro-adjustable ratchet top closure helps secure the upper boot\u003c\/li\u003e\n\u003cli\u003eReplaceable anatomical EVA footbed provides arch support and pedal feel\u003c\/li\u003e\n\u003cli\u003eDurable rubber sole delivers consistent grip for street, sport, and track riding\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":67567774761195,"sku":"34041500","price":529.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/1867799.png?v=1790797994","url":"https:\/\/ctracingservices.com\/products\/alpinestars-smx-plus-v2-vented-motorcycle-boots-black-us-12-eu-47-part-number-2221119-10-47","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
