The lightweight microfiber upper construction offers excellent abrasion resistance while maintaining flexibility for natural foot movement, ensuring comfort during extended use. Strategically placed flex zones, reinforced with textile and soft TPU overlays, facilitate smooth forward and backward motion, reducing fatigue and enhancing control. The innovative ankle brace system provides biomechanical support, limiting hyper-torsion, hyper-extension, and hyper-flexion, while safeguarding the ankle and Achilles tendons against impacts and injuries. This system balances protection with mobility, allowing for precise control and confidence on the bike. The Alpinestars Lace-Lock System, made from durable polymer resin, guarantees quick, secure, and consistent closure, ensuring the boots stay firmly in place during aggressive riding. Additional protective elements include a TPU shifter zone for durability on the medial side, a race-derived TPU shin plate for superior impact and abrasion resistance, and dual-density TPU ankle protectors strategically positioned between the upper and lining to absorb shocks in key areas. For added protection and versatility, the boots feature a replaceable dual-density TPU toe slider with a screw-in assembly, providing comprehensive coverage around the outer toe while maintaining walking comfort. Shock absorption is further enhanced by replaceable heel and external side heel sliders, designed to dissipate impacts and facilitate sliding during falls. Lightweight yet protective, the Alpinestars SMX-6 V3 boots are engineered to give riders a performance edge with a combination of innovative materials and race-inspired features, making them an ideal choice for serious motorcyclists seeking safety, durability, and agility. These boots are finished in a striking black, white, and red graphic design, available in US size 7.5 (EU 41), and built for riders who demand top-tier protection without sacrificing comfort.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAdvanced microfiber upper construction offers lightweight protection against abrasion and high flexibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFront and back flex zones with textile and TPU overlays promote natural movement and impact resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUnique ankle brace protection system provides biomechanical support and limits hyper-mobility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAlpinestars Lace-Lock System ensures quick, secure, and precise closure\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTPU shifter zone enhances durability on the lower medial side\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRace-derived TPU shin plate offers superior impact and abrasion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDual-density TPU ankle protectors positioned for strategic shock absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable dual-density TPU toe slider with screw-in assembly for added outer toe protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable heel and side heel sliders optimize shock dissipation and sliding capability\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":45186906095811,"sku":"34041833","price":349.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/4366824.png?v=1779222955","url":"https:\/\/kellymotorsport.com\/products\/alpinestars-smx-6-v3-motorcycle-racing-boots-black-white-red-graphic-us-7-5-eu-41","provider":"Kelly Motorsports","version":"1.0","type":"link"}
