[OhMy]

A few of the current roster make a point of wiping their feet on the ring apron before entering the ring.

Is it paying homage to a past wrestler or something?

Paying to respect to the wrestling ring.

Back in the early 1900s Wrestling matches used to be outside and their boots used to get dirty. Not only is it like taking your shoes off when entering someone's home but Wrestlers can up infections from a dirty mat.
