Engineered from the ground up for track and sport road use, this uncompromising racing boot pairs a fiberglass-reinforced exoskeleton with a dual-dial closure system that wraps the tibia with millimetre accuracy — because at speed, fit is everything.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTPU protectors at the ankle, shin and lateral impact zones provide professional-grade protection exactly where crashes demand it\u003c\/li\u003e\n\u003cli\u003eFiberglass-reinforced nylon exoskeleton structure delivers maximum structural rigidity without sacrificing essential rider mobility\u003c\/li\u003e\n\u003cli\u003eHigh-density resin dual-dial closure system adjusts independently from both sides for a precise, pressure-free hold that is fully replaceable\u003c\/li\u003e\n\u003cli\u003eLow-profile racing sole maximises grip on footpegs and brake and gear levers, keeping feedback sharp and throttle inputs accurate\u003c\/li\u003e\n\u003cli\u003eAbrasion-resistant high-resistance microfibre construction combines long-term durability with consistent all-day comfort on the track\u003c\/li\u003e\n\u003cli\u003eControlled flex zones and stabilising outer architecture allow fast gear changes and aggressive braking without restricting natural foot movement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuilt for the Track, Refined for the Road\u003c\/h2\u003e\u003cp\u003eThe Rex is a boot worn by professional riders, and every construction decision reflects that origin. The fiberglass-reinforced nylon exoskeleton forms the structural backbone of the boot, channelling and absorbing impact energy away from the ankle and lower leg. Surrounding this core is a suite of TPU protectors — positioned at the ankle, shin and vulnerable lateral surfaces — that meet the demands of high-speed incident scenarios without adding unnecessary bulk to the silhouette.\u003c\/p\u003e\u003cp\u003eThe abrasion-resistant high-resistance microfibre upper holds everything together, resisting slide damage across a wide range of surfaces. The result is a boot that does not feel like armour on the bike — it feels like part of the machine.\u003c\/p\u003e\u003ch2\u003eDual-Dial System: Precision Fit in Seconds\u003c\/h2\u003e\u003cp\u003eThe high-density resin dual-dial closure is the closure technology that sets the Rex apart from conventional buckle boots. Adjustable from both sides of the boot, it conforms precisely to the shape of the tibia, eliminating pressure points and unwanted movement inside the shaft. The system is fully replaceable, making the Rex a long-term investment rather than a consumable. There is no slipping, no hotspots, and no mid-session distraction — just a secure, consistent hold from the warm-up lap to the cool-down.\u003c\/p\u003e\u003ch2\u003eLow-Profile Racing Sole\u003c\/h2\u003e\u003cp\u003eOn track, the relationship between boot sole and footpeg is critical. The Rex uses a slim, sport-tuned low-profile racing sole that keeps the rider's foot close to the peg surface, maximising proprioceptive feedback and ensuring optimal force transfer to the brake and gear levers. Riders who need to feel every input will find the sole geometry exactly right for aggressive, committed riding.\u003c\/p\u003e\u003ch2\u003eSidi Impact Science and Sustainable Responsibility\u003c\/h2\u003e\u003cp\u003eSidi continues to pursue Science Based Targets initiative (SBTi) emission-reduction goals and supports the UN Sustainable Development Goals across its manufacturing operations. The Rex reflects this commitment through the use of long-lasting materials and a design philosophy built around component replaceability — extending the service life of the boot and reducing overall environmental impact.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sidi Rex model 240 in black is a universal racing and sport motorcycle boot suitable for all riders seeking certified track-level protection. Available in sizes 39 through 48 to accommodate the full range of rider foot sizes. Compatible with any motorcycle discipline where a high-performance lace-free racing boot is required — from circuit track days to aggressive sport road riding.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Sidi\u003c\/li\u003e\n\u003cli\u003eModel: Rex\u003c\/li\u003e\n\u003cli\u003eModel number: 240\u003c\/li\u003e\n\u003cli\u003eColour: black\u003c\/li\u003e\n\u003cli\u003eUpper material: abrasion-resistant high-resistance microfibre\u003c\/li\u003e\n\u003cli\u003eProtection: TPU protectors at ankle, shin and lateral impact zones; fiberglass-reinforced nylon exoskeleton\u003c\/li\u003e\n\u003cli\u003eClosure system: high-density resin dual-dial (adjustable from both sides, fully replaceable)\u003c\/li\u003e\n\u003cli\u003eSole: low-profile racing sole\u003c\/li\u003e\n\u003cli\u003eIntended use: track racing and sport road riding\u003c\/li\u003e\n\u003cli\u003eAvailable sizes: 39 to 48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sidi","offers":[{"title":"39 \/ Black - 240","offer_id":53168534880522,"sku":"SY-SIDIREXM-3FC61D-39","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"40 \/ Black - 240","offer_id":53168534913290,"sku":"SY-SIDIREXM-3FC61D-40","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"41 \/ Black - 240","offer_id":53168534946058,"sku":"SY-SIDIREXM-3FC61D-41","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"42 \/ Black - 240","offer_id":53168534978826,"sku":"SY-SIDIREXM-3FC61D-42","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"43 \/ Black - 240","offer_id":53168535011594,"sku":"SY-SIDIREXM-3FC61D-43","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"44 \/ Black - 240","offer_id":53168535044362,"sku":"SY-SIDIREXM-3FC61D-44","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"45 \/ Black - 240","offer_id":53168535077130,"sku":"SY-SIDIREXM-3FC61D-45","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"46 \/ Black - 240","offer_id":53168535109898,"sku":"SY-SIDIREXM-3FC61D-46","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"47 \/ Black - 240","offer_id":53168535142666,"sku":"SY-SIDIREXM-3FC61D-47","price":375.2,"currency_code":"EUR","in_stock":true},{"title":"48 \/ Black - 240","offer_id":53168535175434,"sku":"SY-SIDIREXM-3FC61D-48","price":375.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/juu.png?v=1780808499","url":"https:\/\/inter-pace.com\/products\/sidi-rex-motorcycle-racing-boots-black","provider":"Inter-Pace","version":"1.0","type":"link"}
