" Let’s discuss our Swoosh-less Nike sneaker for a moment. My guess is that if you removed the branding from a pair of Nike Dunk sneakers, they would be worth no more than twenty-five percent of their retail price. That means that at least seventy-five percent of the value of a Nike sneaker is tied up in the emotional elements you can’t see or touch, the intangibles. But just because you can’t see them or touch them doesn’t mean they aren’t real. "
