Featuring an advanced microfiber upper construction, these boots provide lightweight durability and flexibility, allowing for natural movement while maintaining superior abrasion resistance. The front flex zone, crafted from soft microfiber, enhances forward and backward mobility, which is essential during dynamic riding maneuvers. An accordion microfiber panel around the Achilles area offers additional flexibility and supports natural ankle articulation, contributing to overall comfort during extended rides or aggressive riding styles.\u003c\/p\u003e\u003cp\u003eDesigned with rider safety in mind, the SMX Plus incorporates an evolution of Alpinestars' Multi-Link Control system. This system offers external protection and support for the ankle, limiting hyper-torsion, hyper-extension, and hyper-flexion movements that could cause injury. The boots also feature a dual-density thermoplastic polyurethane (TPU) replaceable toe slider with a screw-in assembly, providing reliable protection around the outer toe while allowing easy replacement after wear. Reinforced with a replaceable heel slider and external side heel slider, these boots effectively dissipate shock and facilitate sliding during falls, enhancing rider safety.\u003c\/p\u003e\u003cp\u003eMaximum flexibility and comfort are achieved through large asymmetrical accordion zones at the front and rear of the boots, which are optimized to allow natural foot movement. The micro-adjustable ratchet closure system ensures a secure fit with easy adjustment, while the inner instep speed lacing and lateral zipper enable precise and quick donning and removal. The innovative Lace-Lock System, made from advanced polymer resin, ensures a secure closure, preventing accidental loosening. Additional protective features include a contoured high-modulus shin plate for impact and abrasion resistance, along with an anatomical, replaceable EVA footbed that offers excellent arch support and a responsive pedal feel. The advanced synthetic forefoot lining, laminated with open-cell foam, provides shock absorption and breathability, maintaining comfort during long rides. The durable rubber sole offers consistent grip and a refined riding feel, rounding out these high-performance motorcycle boots.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLightweight microfiber construction for high performance and flexibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFront flex zone with soft microfiber for enhanced movement and abrasion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAccordion microfiber panel around Achilles for natural ankle movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStretchable accordion panel outside entry\/exit for easy fitting\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMulti-Link Control system for ankle support and impact protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable dual-density TPU toe slider with screw-in assembly for enhanced toe protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable heel slider and external side heel slider for shock absorption and sliding safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAsymmetrical accordion zones at front and rear for maximum flexibility and comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMicro-adjustable ratchet closure for a secure fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInner instep speed lacing closure combined with lateral zipper for precise fitting\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLace-Lock System made from advanced polymer resin for quick, secure closure\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\u003cul\u003e\u003cli\u003eAnatomical, replaceable EVA footbed for arch support and pedal feel\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 all-day comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable rubber sole with textured grip for consistent riding feel\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":45186753462467,"sku":"34041470","price":539.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/1867500.png?v=1779211082","url":"https:\/\/kellymotorsport.com\/products\/alpinestars-smx-plus-motorcycle-boots-black-white-red-fluorescent-us-7-5-eu-41-part-number-2221019-1231-41","provider":"Kelly Motorsports","version":"1.0","type":"link"}
