For Douglas Clark, the darkest part of working for Nike in the 1980s was watching American shoe manufacturing "evaporate" in the Northeast in a mass exodus to Asia in pursuit of cheaper labor.
"As a true Yankee — and my father was a Colonial historian — you know, it was heartbreaking," he said.
Clark would go on to a long career in footwear, at Converse, Reebok, Timberland, then his own line of shoes at New England Footwear. And there, he would devote eight years to one mission: creating a model to make shoemaking in America profitable again.
This was a tall order. At a time when President Trump speaks of rebuilding American manufacturing, footwear is a telling example of how hard it is to turn back time.
