I thought about getting one, but when I went to a running shoe store to get new shoes (I was getting blisters with the old ones) they said the shape wasn't good for my foot. I liked the idea too =(
EDIT: nm, I'm a dork. I thought you were talking about the shoes that had that in them... I suppose I should check out the link before I post...
