At "Kinky Boots, " the dancing is done by factory workers, who would be out of character breaking into fancy footwork, and drag queens in six-inch stilettos, which aren't designed for pirouettes.
"Kinky Boots, " which opens April 4, is based on an obscure 2005 British film about a British shoe factory on the brink of ruin that retrofits itself into a maker of fetishistic footwear for drag queens.
