Purely out of interest I did a Google search on "manly footwear" and "if a man needs footwear"

Result "manly footwear"" - 34 "If a man needs footwear"- 5
(all copied from the same source)

But really, all you have to do is ask yourself, would Merle Haggard really have written such a meaningless line as "Leather boots are still in style if a man needs footwear" ?
