“I think you guys are pushing it a little bit.”
nike and all its scientists and engineers disagree. not that they’re all correct. but you’ll remember the speed skating like suit marion jones wore a few years ago.
Nike also spent an astronomical sum to validate the aero zip shroud over exposed laces. When they actually stated the data, the difference was a whopping total of less than 10 centimeters for a word class sprinter over the course of 200m. Even then, it only ended up on three of their shoe lines (MJ Sprint/JSC, Celar, Superfly). Is ten centimeters, even less for a mere mortal, really worth the tunnel time? When it comes down to OG, maybe…but most races at 200m are won by more than that.
