SIDI Crossfire 3 SRS Boots

The legendary Crossfire line has evolved again. The SIDI Crossfire 3 SRS Boots have been completely redesigned, with only the acclaimed SIDI cam lock buckles and straps carrying over from the Crossfire 2 SRS Boots. The inner gaiter has a larger circumference than the Crossfire 2, accommodating an even wider range of calf sizes and making for a tight seal around the rider’s lower leg no matter what knee brace system may be used. The upper inside of the gaiter features a suede heat protection-grip panel for maximum grip. The Dual Flex ankle has been redesigned to prevent motion beyond anatomical limits that may cause injury, without restricting dexterity for normal shifting and braking. The SIDI Crossfire 3 SRS Boots are possibly the most durable, serviceable motocross boots on the market - the design uses hardware instead of stitching so virtually every part is replaceable, season after season. 

Dual Flex System:

• The Dual Flex system used on the SIDI Crossfire 3 SRS does not only limit lateral hyperflexion, but also features hard stops at the limit of the anatomically allowed range of motion that limit hyperextension of the ankle joint.  The adjustabillity of the exclusive Dual Flex system with its four floating independent straps enables the Crossfire 3 SRS boots to provide each rider with a personal fit no matter their body shape or whether or not knee braces are used. 

Adjustable Calf System:

• Sidi's exclusive double adjustable calf plate system allows the rider to adjust the inner diameter of the Crossfire boots at the calf. This system, along with longer upper straps, allows the Crossfire 3 SRS boot to accommodate riders with larger calves much easier than even the previous Crossfire 2 Boots. The inner plate is made of two different materials; a rigid one to support the boot and a heat resistant one to protect the rider's leg from exhaust heat. The new inner heat shield is made of a high grip material.

Non-Bootie Design:

• Sidi boots do not incorporate inner booties into their design, and for good reason. Booties make the design larger and cumbersome, add to the boot's thickness, which interferes with shifting. Plus, inner booties retain body heat affecting the rider's performance and comfort.

Buckles:

• Cam-lock buckle system incorporates a strap memory retention system.
• Adjust the straps once and they will be at the same position for every ride after that. No more readjusting for every ride or mid-day during a ride.

Toe:

• The tip of the toe on the Crossfire is covered with plastic to protect the base material and seams against abrasion from brush, etc. Plastic shift and brake lever guards on the top of each foot area.

Improved Fit:

• Sole boat features a more cupped and thicker design so the rider’s foot rests deeper into the sole system
• Removable arch support

Other Features:

• New ankle pivot system designed to have a hard limit of foot/ankle hyperextension
• New sole boat features a more cupped and thicker design so the rider’s foot rests deeper into the sole system
• New Dovetail SR anti-skid rubber sole covers the arch area of the sole and is replaceable using hand tools
• Toe and heel areas on the Dovetail SR sole are now a permanent part
• Laminated Technomicro base material in all areas
• Slim, cool non-bootie design
• Calf plate system features an inner double adjustment that expands to fit the largest calf or knee brace system
• Nylon insole
• Inner heat shield made of high grip material
• Removable arch support
• Toe area covered in protective plastic
• New rigid, shock resistant, anatomically shaped heel hold the riders foot firm and thus resists twisting while offering added protection
• Replaceable, sleek, micro adjustable cam lock buckle system with memory retention nylon straps
• All buckles move independently of each other and have just one fixed point (by a screw) which allows easy closure and the buckles can adapt to the rider’s position as they pivot on the mounting screw as the rider changes position on the bike
• Lower buckle guards help protect against opening due to an impact
• Complete central strap system can be easily replaced and is available in two sizes
• Lined with anti-abrasion Cambrelle in the foot area for comfort, the upper is lined with Teflon mesh which prevents complete absorption of water and sweat. These materials will not retain water or sweat on the inside of the boot. The boot will dry quickly and the treatment also prevents the onset of mold
