Gosh after seeing those apart, its hard to see how they come up with a $720 price tag looks like they are probably $30 to make lol...and I love it how they kept saying they were going to release a power-lace shoe for more of the "general public" yet they only release them in a handful of stores...way to go Nike.
I know.... I guess I shouldn't be surprised. I am little disappointed now that I see the actual mechanism. Don't get me wrong, a self-lacing shoe is cool and Nike made something that will hopefully hold up. That being said, that is a pretty basic system that could be prone to the gears breaking inside the mechanism (I could be wrong though and maybe they will hold up the lifetime of the shoe).
I was hoping to be able to purchase a pair at some point, however, this is Nike, and their most popular and innovative products are usually unattainable by the general public. They obviously market that way for a purpose (which alienates its customers), but also builds hype for their products.
