I was lucky enough to get one of the first test pairs of the @on Cloudboom Strike LightSpray, which I wrote about for @time’s Best Inventions issue (out now!). Last night, I got to see the manufacturing process in action: That automated robotic arm sprays 1.5 kilometers of an elastic thermoplastic material onto a performance midsole, and you’ve got a brand new pair of super shoes in three minutes (I sped this video up 3x to fit it all in). #onrunning #running #runningshoes #runtok #runner
