run
走 centers on the action of running: moving quickly on foot.
走 is a pictograph of a person running, with the top 土 originally representing a swinging arm and the bottom 龰 a foot in motion.
The top 土 looks like a runner's pumping arms, and the bottom 龰 is a foot in motion. Together they show a person running.
For ソウ, imagine a runner dashing through a field of tall grass, making a soft 'sow' sound as they go: sow -> ソウ.
