The front flex area, made from soft microfiber, enhances abrasion resistance while allowing natural forward and backward movement. The flexible accordion microfiber on the Achilles area provides additional natural movement and comfort. An external stretchable accordion panel ensures a snug fit for easy entry and removal, optimizing convenience and support during rides. The innovative Multi-Link Control system, evolved from Alpinestars' signature design, delivers external protection and support for ankle articulation, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion while safeguarding the Achilles and ankle from impacts. The boots incorporate a dual-density thermoplastic polyurethane (TPU) replaceable toe slider with a screw-in assembly, offering durable coverage around the toe area, and feature replaceable heel and side sliders that dissipate shock and facilitate sliding during falls. Large, asymmetrical accordion zones on the front and rear enhance flexibility and comfort, ensuring maximum rider safety. The micro-adjustable ratchet top closure with a stow tab end allows for a precise fit, while an advanced synthetic forefoot lining laminated with open cell foam provides shock absorption. Breathable linings in the ankle and leg areas deliver added comfort during extended rides. The anatomical, replaceable EVA footbed offers arch support and a firm pedal feel, contributing to overall riding stability. The durable sole, textured for consistent grip, improves rider feedback and control. Inner instep speed lacing closure combined with a lateral zipper ensures a secure, customized fit. The Alpinestars Lace-Lock System, made from advanced polymer resin, allows quick and reliable fastening, with a hook-and-loop tab locking the zipper pull flat for safety. A contoured high-modulus shin plate provides superior impact and abrasion resistance, making these boots an ideal choice for serious motorcyclists seeking protection, comfort, and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLightweight microfiber upper construction for enhanced protection and flexibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFront flex area with soft microfiber for improved abrasion resistance and movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAchilles area with flexible accordion microfiber for natural movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStretchable accordion panel on outside entry\/exit for a snug fit and easy removal\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMulti-Link Control system providing external ankle support and limiting hyper-movement\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 to absorb shock and facilitate sliding\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAsymmetrical accordion zones on front and rear for maximum flexibility and comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMicro-adjustable ratchet top closure with stow tab for a secure fit\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 ankle and leg linings for added comfort during extended use\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAnatomical and replaceable EVA footbed offering arch support and pedal feel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable textured rubber sole for consistent grip and rider feedback\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInner instep speed lacing closure and lateral zipper for a precise fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAlpinestars Lace-Lock System for quick, secure fastening\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHook-and-loop tab to lock zipper pull flat and safe\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eContoured high-modulus shin plate for superior impact and abrasion resistance\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":45186753364163,"sku":"34041482","price":539.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/1867563.png?v=1779211056","url":"https:\/\/kellymotorsport.com\/products\/alpinestars-smx-plus-motorcycle-boots-black-white-yellow-fluorescent-us-8-eu-42-part-2221019-125-42","provider":"Kelly Motorsports","version":"1.0","type":"link"}
