The Crossfire 3 SRS is purpose-built for riders pushing their limits. Its advanced structure adapts to your body with four adjustable locking straps, replaceable “Easy Action” cam lock buckles, and a customizable calf system for a snug, supportive fit. Closed-cell foam enhances comfort while maintaining secure hold, so you stay dialed-in during every ride—no matter the terrain.

SIDI was the first to introduce hyperextension control in motocross boots, and the Crossfire 3 SRS is the refined result of that innovation. Its dual-sided hinge pivot glides to a hard stop to prevent hyperextension and hyperflexion, while still allowing a natural range of motion. A shock-absorbing heel cap boosts rear foot protection, and the adjustable shin plate accommodates knee braces for added versatility and coverage.

Protective where it counts, flexible where it matters. The Crossfire 3 SRS features a structured flex zone and body-hugging shield that covers key impact areas. An adjustable tibia plate and inner panel system allow each rider to fine-tune the fit for personal comfort and control. Inside, an Air Teflon Cambrelle® mesh lining disperses moisture, prevents odor and bacteria buildup, and protects the structure of the boot—keeping your gear fresher for longer.

The SRS (Sole Replacement System) gives you the freedom to swap out your worn sole in seconds, whether you're refreshing the tread or switching to the optional Enduro sole for more aggressive terrain. Built for traction, durability, and versatility, this system ensures you're always riding with the performance grip you need.

Crafted from premium materials and made for long-term use, the Crossfire 3 SRS doesn’t just endure—it evolves with your ride. Every key component is replaceable, making the boot easy to clean, maintain, and refresh over time. With legendary SIDI construction, this is the boot that’s with you for the long haul.
