I just watched a documentary on Tinker Hatfield, a shoe designer for Nike. It's called "Abstract" and it is on Netflix if you want to check it out. Tinker talks about how, after 10 years, pro basketball players' feet are trashed. They have to tie their shoes too tightly because of all the stopping and starting and cutting and jumping they do. But, he said, what if, when a player was at the free throw line, the shoe could loosen, allowing blood flow to the foot, and then sense when it was time to tighten up again? What if when the player was subbed out, or there was a time out, or a television break, the shoe could loosen automatically? It would help keep players' feet from being so damaged.
This is step one. This is the MacBook Air that Steve Jobs pulled out of the manila envelope.
