You may have seen shoes like this before, but these are much easier to tinker with, if you're into that. We're not advertising the kit as programmable, but I'm sure the HN crowd will figure out how to hack it.
On a personal note, there's no big (or small) company behind this project. A group of friends launched it primarily to help sustain our growing Burning Man camp. This is our first foray into manufacturing electronics at any kind of scale, so any help you can provide the project will really make a difference!
