“Play by the rules, but be ferocious.” — Phil Knight
The story of the Nike Waffle Trainer is one of the great invention myths in business history — and unlike most invention myths, this one is essentially true. Bill Bowerman, tinkering in his kitchen on a Sunday morning in 1971, looks at his wife’s waffle iron and has an idea: what if the waffle grid pattern could be applied to a running shoe sole?
He pours rubber into the waffle iron and ruins it. He pours rubber into another waffle iron (his wife Barbara is now several waffle irons poorer) and succeeds. The result is a sole with a distinctive waffle pattern that provides superior traction on a variety of surfaces while being significantly lighter than conventional shoe soles.
The Waffle Trainer — officially introduced as the Nike Waffle Trainer in 1974 and reaching mass production by 1975 — is a breakthrough not just in running shoes but in athletic footwear generally. It demonstrates that genuine innovation, born from an athlete’s deep understanding of what runners need, can create a product category-defining moment.
The timing is perfect. The late 1970s see the beginning of the running boom in America — millions of middle-class Americans beginning to run for fitness, not just competition. These new runners need good shoes but aren’t elite athletes. The Waffle Trainer serves them perfectly: high performance, reasonable price, and a distinctive visual identity that makes it instantly recognizable.
The jogging craze of the mid-1970s — sparked by books like Jim Fixx’s The Complete Book of Running — transforms the athletic shoe market overnight. Running goes from a fringe sport of obsessives to a mainstream American activity. Demand for quality running shoes explodes.
Nike is positioned perfectly. The company has the performance credentials (worn by elite athletes at major competitions), the product innovation (the Waffle Trainer), and the brand story (built for real runners, by people who run). Revenue grows at extraordinary rates — 50%, 100%, more — year after year.
With explosive growth comes organizational chaos. Nike in 1975-77 is simultaneously a startup and a mid-sized company, lurching between the two identities without fully committing to either. Knight must hire, build systems, create management structures — none of which come naturally to a man who describes himself as fundamentally shy and deeply uncomfortable with conventional management.
The “Kitchen Cabinet” — an informal group of early team members who gather at Knight’s home to make major decisions — cannot survive the scale the company is reaching. Real organizational structure is required. Knight is reluctant to put it in place, in part because structure means losing the scrappy, anything-goes culture that has driven so much of Nike’s early success.
The relationship with Nissho Iwai, the Japanese trading company that has been financing Nike’s growth, becomes increasingly complex. Nissho’s executives are loyal partners and shrewd observers of American business culture. They give Knight latitude that no American bank would — but they are also not passive. They have their own interests, their own views on Nike’s strategy, and their own ideas about how the relationship should evolve.
Knight navigates this relationship with increasing sophistication, learning the particular art of Japanese business negotiation: patience, respect, indirect communication, and the long view.
How does your organization handle the tension between the scrappy startup culture that created its early success and the structure it needs to survive at scale? What do you risk losing, and what do you gain?
