SIDI Crossfire 3 SRS Boots

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.
