Sidi Crossfire 3 SRS Boots Black.  They are the third generation of Sidi's most advanced Off-Road boot. Made of Techno Micro with PU inserts, they stand out for affording high levels of comfort and protection. With an internal tongue with internal bellows and joints lined in micro-porous material to keep water out.
 

Joints

Just like the Crossfire 2, the Crossfire 3 have 2 joints: the first on the lower part of the ankle and avoids hyperflexion of the ankle, instep and Achilles heel in the event of forward or backward leg flexion. The second joint is on the shaft of the boot and improves freedom of movement and fit. In this way, they allow for a custom fit to each rider irrespective of their physical constitution or the use of knee guards. The rear of the boot has PU protection with logo.

 
Calf adjustment system

Sidi's exclusive and patented system allows the adjustment of the diameter of the Crossfire 3 on the calf. This system, together with longer adjustment straps, represents an advance in terms of comfort. The inside of the boot is made of 2 different materials; a stiff plastic one affording support to the boot and another heat resistant one to protect the rider's leg from the heat of the exhaust pipe. All the components of the system are replaceable.

 
Heel

The heel structure has been redesigned to afford greater protection to the foot in the event of torsion. It has been made of PU and affords greater comfort and stability.

 
Design without bootie

Sidi boots do not have an inner bootie. According to those in charge at Sidi, booties require a wider boot structure, which interferes with shifter use and retains body heat affecting the features and the rider's comfort.

 
Closures

The system has 4 micro-adjustable buckles with memory, locking retention straps. The straps only have to be adjusted once and they stay in this position for each outing. All the buckles are easily replaceable. The central strap is replaceable via two screws.

 
Toes

The toes are protected with plastic material with serrated relief for greater grip. With metatarsal protection.

 
Removable SRS Sole

The new replaceable SRS sole is a little bit higher in order to provide better grip. The toebox and the heel are fixed whilst the central part, subject to wear, can be changed via 4 screws. The toebox offers small teeth for greater grip (perfect for Enduro) and the heel has a soft PU insert for greater stability.

 
Interior

Interior made of Teflon mesh fabric and Cambrelle. The Teflon prevents the absorption of water and sweat, as well as providing fast drying and preventing fungal growth. Cambrelle is a highly abrasion polyamide lining and affords fast moisture wicking. The upper part is made of soft mesh and had padding in the shin area.

 
Other features:

• Malleus with ergonomic foam padding to adapt to the shape of each foot.  
• Upper extremities with elastic bellows and Velcro closure to keep gravel and dust out of the boot.  
• Anatomical PU front plate, replaceable via screws.  
• Removable stiff Nylon insert inside the boot.
