Snowboard binding rotating devices are designed to minimize the torque force that occurs when a snowboarder has one foot out of the binding and one locked on the board. The rotating device allows the snowboarder to turn the locked foot straight into the direction of the tip of the snowboard without removing his boot from the boot binding. Like this he can push himself forward like a skateboarder.
Snowboard boot bindings are normally screwed onto the snowboard in a permanent orientation which is almost perpendicular to the direction of travel of the snowboard. When a snowboarder reaches the bottom of a run, the rear boot is typically released from its binding to allow the snowboarder to propel himself forward across relatively flat snow. Because the front foot in the snowboard binding is at an angle to forward motion, the snowboarder experiences discomfort and tension on his leg, knee and foot joint.
Four to 8 percent of snowboarding injuries take place while the person is waiting in ski-lift lines or entering and exiting ski lifts. Snowboarders push themselves forward with a free foot while in the ski-lift line, leaving the other foot (usually that of the lead leg) locked on the board at a 45- to 90-degree angle, placing a large torque force on this leg and predisposing the person to knee injury if a fall occurs.  
The rotating device is usually installed between snowboard and binding or integrated into the binding. It allows the snowboarder to rotate the snowboard boot binding in relation to the snowboard by pulling upon a tether or releasing a lock. Repeating and rotating in the opposite direction leads back to the original angle position.
