Turns out real science is involved. Nike brings many of its athletes to Oregon, pushes them through elaborate stress tests in the company’s state-of-the-art training lab, breaks down their running mechanics and foot structure (and also how those two things relate), then builds the best possible shoe for them. Like how you’d build a mouthpiece for someone’s specific mouth, only for feet, and only after measuring how someone talked and chewed food for an entire weekend.
