Uncompromising Protection

When it comes to safety, the Rex Boot leaves nothing to chance. Its internal support structure is built from high-grade TPU and an external fiberglass-reinforced exoskeleton for maximum impact resistance. Designed to maintain integrity during high-speed crashes, the boot also supports controlled sliding—helping dissipate force and reduce injury in racing scenarios. In the Rex, protection is built in from every angle.



Tailored Fit

The Rex Boot wraps the tibia like no other, thanks to its dual-sided adjustment system. Featuring a proprietary high-density resin dialing mechanism, it offers micro-precision fitment that’s both smooth and secure. Built to last and fully replaceable, this closure system ensures every rider gets a custom fit that holds firm—whether you're leaning deep into corners or pushing out of the apex.




Firm Support, Enhanced Control

SIDI’s Firmor technology anchors your foot in place for exceptional stability and response. Designed to eliminate unwanted movement inside the boot, this internal structure keeps your foot planted during aggressive maneuvers. Reinforced protection at the ankle, heel, and tibia adds security without sacrificing feel—so you stay fully in control, even under pressure.

Maximum Feel, Minimal Bulk

Built with high-abrasion-resistant microfiber and a low-profile racing sole, the Rex delivers direct feedback and confident grip on the pegs. It's lightweight, breathable, and race-tuned for riders who demand precision and comfort at every turn. Whether you're chasing lap times or carving canyon roads, this is the boot that puts performance underfoot.
