With a completely revolutionary technology, the Crossfire 3 SRS boot features a jointed flex system at the ankle called "Hyper Extension Bloc."
It prevents hyperextension of the ankle, instep, and tendon in the hindfoot when the leg is bent forward or backward.
This technology ensures the rider's safety.
