Constructed with a lightweight microfiber upper, these boots provide excellent abrasion resistance and flexibility, enabling natural movement during aggressive riding or long-distance journeys. The front flex zone, made from soft microfiber, enhances forward and backward mobility, while the accordion microfiber on the Achilles area offers additional flexibility and support for natural ankle articulation. An external stretchable accordion panel at the entry point ensures a snug fit and effortless donning and removal, making these boots both practical and comfortable.\u003cbr\u003eAlpinestars' innovative Multi-Link Control system offers external ankle protection by limiting hyper-torsion, hyper-extension, and hyper-flexion movements. This system delivers exceptional ankle support while safeguarding the Achilles and ankle from impacts. The boots feature dual-density TPU replaceable toe sliders with screw-in assemblies, providing durable protection around the toes and allowing easy replacement after wear. Additional impact absorption is facilitated by replaceable heel and side sliders, positioned to dissipate shock during accidents and promote sliding to reduce injury risk.\u003cbr\u003eThe design emphasizes maximum flexibility with large asymmetrical accordion zones on the front and rear, optimizing comfort and safety. The micro-adjustable ratchet closure system ensures a secure fit, with a stowable tab for convenience. The advanced synthetic lining in the forefoot, laminated with open-cell foam, offers shock absorption, while breathable materials in the ankle and leg areas maintain comfort during extended rides. An anatomical EVA footbed, which is also replaceable, provides arch support and a tactile pedal feel, enhancing rider control.\u003cbr\u003eThe sole is crafted for durability and grip, featuring a textured rubber surface that delivers consistent traction on various surfaces. Inner instep speed lacing combined with a lateral zipper allows for precise fit adjustments and quick removal. The Alpinestars Lace-Lock System, made from advanced polymer resin, secures the laces firmly for added safety. A hook-and-loop tab locks the zipper pull in place, preventing accidental opening. Additional protection is provided by a contoured high-modulus shin plate, offering excellent impact and abrasion resistance, making these boots ideal for demanding riding conditions and competitive environments.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLightweight microfiber upper construction for enhanced flexibility and abrasion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFront flex zone with soft microfiber for natural movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAchilles accordion microfiber for increased flexibility and support\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStretchable accordion panel at entry for a close fit and easy wear\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMulti-Link Control system provides external ankle protection and support\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDual-density TPU replaceable toe slider with screw-in assembly for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable heel and side sliders for shock absorption and sliding safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLarge asymmetrical accordion zones for maximum flexibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMicro-adjustable ratchet top closure with stowable tab\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdvanced synthetic forefoot lining laminated with open-cell foam for shock absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBreathable lining in ankle and leg areas for enhanced comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAnatomical, replaceable EVA footbed for arch support and pedal feel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable rubber sole with textured grip for consistent traction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInner instep speed lacing closure and lateral zipper for secure fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAlpinestars Lace-Lock System for quick, precise lacing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHook-and-loop tab to secure zipper pull\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eContoured high-modulus shin plate for impact and abrasion resistance\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cdiv class=\"product-template\"\u003e\n\u003cbr\u003e      \u003ch1\u003eAlpinestars SMX Plus Motorcycle Boots - Black\/White\/Red Fluorescent, US 10.5 \/ EU 45, Part Number 2221019-1231-45\u003c\/h1\u003e\n\u003cbr\u003e      \u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003eThe Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, combining advanced protection with superior comfort.
