[See also the original glyph 赱 dirt with emphasis on taut sliding] Combines「ground, soil, dirt」with「foot or feet, astride」to describe RUNNING. Technically, RUNNING occurs when an animal propels itself with its legs and feet in a manner that causes all of its limbs to be off the ground simultaneously. For a brief moment during each step, the subject is TAKING FLIGHT, leaving the surface of the Earth and becoming airborne to enter the divine zone known as heaven: there are at least three possibilities for 'heaven': in literature and ecclesiastical philosophies, 'where the gods and spirits dwell.' In astronomy as 'outer space' with stars and galaxies. And traditionally as the space that surrounds us, the atmosphere and sky of our planet. For example, elephants technically never run, since at least one foot remains in contact with the ground at all times (elephants can walk fairly fast, however). When an animal RUNS, it enters the heaven of the atmosphere, just briefly.
RUNNING is when all one's feet are lifted off the ground, and not when hitting the ground as some have suggested. Other glyphs also describe CHANGING SHAPE OR FORM to become divine as a TRANSFORMATION or METAMORPHOSIS, notably those related to having one's feet no-longer-integrated to transform into the「erotica」of a dynastic Chinese service provider, and no longer using one's feet on the ground (化)…in these cases however, this was a permanent change until the end of one's natural life. It is clear with usage that the elements combined in this glyph (「erotic foot and night soil」or,「erotic foot with screwing rod」or,「divine on taut erection with vertical rod motions in flesh seam」) are not always about moving without any hindrance, restraint, running, or moving swiftly on foot so that both or all feet are not on the ground during each stride, unless referring to the feet of the service provider moving swiftly and held above the floor by a client, or, two clients, as depicted in erotic Chinese art:「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)

Oldest form (赱) comprised of「soil, feces」with「emissions up while taut」or「emphasis on taut head sliding.」走 combines「ground, soil, feces」with「erotic foot or feet, tension for a long time with gasping, someone divine raised with person, a rod raised of a person」to mean RUN. Perhaps also as running 'to get some,' and not referring to a human with no-longer-integrated feet for whom running is an impossibility. Lower element as「busted feet」is a person physically unable to run, and hardly able to walk or even stand unaided at times, so this glyph must be referring to various actions of the clientele.
Like it or not, elements are also「fecal erotica」that causes a pool of diarrhea-like slurry to form near the rectum, particularly after multiple accesses by a gang of paramours, RETREATING, TAKING FLIGHT, THE RUNS caused by「changing shape or form」of firmer feces into a thoroughly blended mixture of gel-like slurry (see 趦, 湗), another reason that early bonobo-humans ran in clustered groups: a SPAWNING RUN, that needs no further explanation, the FIRST CATCH OF THE SEASON as males running to be the first in line with the shaman's new crop, ewe lambs, or, a new group/gang member (see 奔).
Some true die-hard fisherman might still be inclined to RUN for the FIRST CATCH OF THE SEASON, often during a「spawning run」but by late in the season or late in life that may have become a bit tedious. Note that most fish without legs don't actually「run to spawn」nor do they even travel far to do so…another English expression that perhaps originated in Chinese.
