The Crossfire 2 SRS is Sidi’s flagship off road boot that delivers extremely technical features in a pro-level boot, and improvements on the Crossfire’s first generation. With a more rigid feel and slightly narrow fit than most other boot options, the Crossfire 2 SRS is designed around locking your foot down and protecting it with stiff materials while still giving you good range of motion and flexibility.
The upper is largely made of impact resistant TPU panels with the modular type of construction allowing every panel to be entirely replaceable. The design provides massive protection to both your leg and ankle, which increases even more when joined to the lower boot via Sidi’s dual-hinge system. This hinge system dramatically improves both impact and rotational protection with its double pivots providing a very large and surprising range of motion considering how stiff the boot's protection is overall.
The Sole Replacement System (SRS) allows very quick, very easy sole changes you do yourself using specialized soles and integrated flathead fasteners. You won't see this sole design on any other boots and on the Crossfire 2 it works very well, has multiple types of sole you can choose from, and it pairs well with the more narrow width of the sole and the rigid feel of the boot.
To manage all the stiff protection, the interior is covered extensively in 3mm Technomicro fabric and moisture-wicking materials that help your foot breath and avoid uncomfortable pressure points. The lack of pressure or pinch points is more impressive since Sidi steered away from an inner bootie design, deciding instead to keep the boot profile slim and breathable without any unneeded layers.
On the whole you can look at the Crossfire 2 SRS Boots as a lifetime piece of gear that will not lose its stiffness or support as it ages. Protection is superior to most other options, and while the boot is significantly rigid, comfort is on par with other premium boots because of the interior fabrics and the secure hold the boot has on your foot. Choose the type of SRS sole you want, replace any bolt-on piece if it gets daaged, and the Crossfire 2 SRS Boots will be a great choice for years of track, enduro, even supermoto riding.

Replaceable shin plate
The shin plate is made in nylon and it is inserted on a polyurethane frontal support. Both parts are replaceable.
Replaceable metatarsus insert
A rigid replaceable nylon insert has been added to protect the inside of the boot in case the rider’s foot slides o ff the foot peg or if it slips off the kick-starter. The insert is replaceable by unscrewing the 4 screws.
Micro adjustable and replaceable buckle system
The Crossfire 2 utilizes four micro adjustable buckle closures, with indented memory-regulation straps. The buckles, straps and retaining clips are easily replaceable. The buckles have just one fixing point (by a screw), which allows them to be easily replaceable. You will note that all four buckles work independently from each other. This system allows the boot to fit all shapes of feet and lower legs independently making each boot that much more comfortable for each individual rider.
Adjustable calf system
The boot leg has a replaceable inner polyurethane plate with a heat resistant rubber insert to protect the leg from exhaust heat, wear and tear. The calf plate features an inner double adjustment, which allows to widen the circumference of the boot and accommodate even the widest calves and knee braces.
Dual flex system upper
The Crossfire 2 maintains the key feature of the Sidi Flex system, with its two articulated joints. The first lower one, on the ankle, improves leg flexation and allows for a more natural and correct position on the foot pegs. All bolt on components of the Crossfire 2 are replaceable. The upper pivot, on the bootleg, improves the boots flexibility and the adjustment of the bootleg itself. In this way, the rider can adjust the boot strap at the calf to his personal preference and achieve an improved fit.
