It looks like there is a split-end dual plug charger included with the shoes, so we think there’s likely a small lithium polymer battery with a charger built in to each shoe. The tip is usually for a 5v source, but we’ll see what it is later.
There are 12 LEDs and 2 EL panels (possibly 3, but likely 2 per shoe). The auctions are well over $4k so we don’t think we’ll see an iFixit style teardown to figure out what NIKE put together for the electronics, so for now – we’re just going to guess.
Electronics in shoes is tricky, we’re working on a fun project around this, stay tuned 🙂
