This is the only reference to movement that the standard makes, and has become an area that is poorly understood. However, since this is a rather "normally" structured moderate dog, it should show "normal" dog movement. In other words, the dog should move like and athlete. At slower speeds, his footfalls will tend to be farter apart, and as speed increases, his feet will tend to converge toward a centerline under his body. This is the only way the dog could move as the standard describes, without rolling his body. He should trot, not pace. He should show moderately good reach, and his rear legs should drive him powerfully. His well-arched feet, moderate angulation, powerful muscles, and generally good physical condition should provide him with a springy gait. All normal dog movement criteria should apply. He should not paddle, toe out, cross, weave, ect. The front and hind feet should strike approximately the same distance apart, leaving tracks in two lines, rather than 3 or 4. The reference to springy gait denotes not only athleticism, but a state of mind. The dog should appear light on its feet, and ready for whatever happens. It should never plod, or move in a listless or dull way.
