I believe that the Roman pace was defined as the distance between heel

heel strike of the other foot is a bit long - 30 inches is the US Army
marching standard.

...and double that would be 5 feet, which is pretty close to the
back formed 5.28 feet.  However, modern estimates are that the
Roman mile was actually 4680 feet, so a slightly shorter stride
than the modern US Army version. Since, so far as I know, mondern
people are, on average, somewhat taller than in the past, this
pretty much works out.

A step is the distance between successive feet hitting the ground.
A pace is the distance between the same foot hitting the ground twice.
Note that the English word 'mile' is derive from the Latin 'mille',
or "one thousand".
