The concept of 3D Printers making you anything you want still blows my mind, but this guy for a shoe company Wiivve (pronounced Weave) ran in flip flops yesterday. Clearly it's a marketing ploy trying to prove they're just as comfortable as sneakers even for crazy distance. However, for a marathon these look just as silly to me as those "toe shoes". I'll stick to sneakers for running, but it is impressive he finished in the flops... maybe for every day wear.
