Is that right? I have not heard that...although I can see the derivation. Perhaps regional?
The "cone" of the last is the part that corresponds to the instep of the foot.
A shover is a fairly thick piece of leather intended to be used with a wedge to adjust the instep girth on "comb lasts"--lasts with flattened cones. And to allow the last to be pulled from the shoe.
The case can be made that the shover, mechanically and functionally, takes the place of the cone of the last.
AFAIK, "shovers" became obsolete, both in practice and in the language, when hinged or "slip cone" lasts were invented.
