The Sidi ST and ST Air have incorporated the Cam Lock buckling system from the Sidi off-road boots and included them on the closure system. The Cam Lock buckles are hands down the best off road boot closure system. Adding these buckles to a street model will ensure a secure and comfortable closure around the calf. The buckles also allow for a quicker “in and out” while still being very protected and locked while riding.
