Many of the verses that I found refer to feet "covering up the whole sidewalk" or "feet making a hole in the ground".

Here's two examples from Dorothy Scarborough "On The Trails Of Negro Folk Songs" {Folklore Associates Edition, 1963; originally published by Harvard University Press, 1925}

OL VIRGINNY NEVER TIRE {excerpt}
There is a gal in our town,
She wears a yallow striped gown.
And when she walks the streets aroun'
The hollow of her foot makes a hole in the groun'.
{p. 109}

GREAT BIG N----R SITTIN' ON A LOG {excerpt}
My gal , she's a big town talk,
Her foot vovers de whole sidewalk,
Her eyes like two big balls o' chalk,
Her nose is lak a long cornnstalk.
Sister Mary, you shall be free,
In de mawnin; you shall be free.
Po' mourner, you shall be free,
When de good Lawd set you free.
{p. 176}
