I guess this is interesting, but have they thought about the future yet? The materials needed will make the environment WORSE. They can't be recycled, so like other garbage and trash, it will have to (slowly) decompose in a dump! Think about it. And really, do we even need some animated footwear? No, we don't, it's a waste of money to buy. Great idea and all, but compulsive shoppers are the only ones that will purchase this product, hopefully. Sorry to down the idea, though.

one advantage is that they are a cool shoe and the disadvantage is that you have to have a tip of phone to use it on :) :)
