Today, 3-D-printed shoes are luxury experiments. Here's what it'll take to make shoes people actually want (and can afford) to wear.
The premise was promising. United Nude, a footwear company known for its experimental designs, enlisted five industry heavyweights to create 3-D-printed high heels that pushed the limits of the technology. Partner 3D Systems would manufacture up to 50 pairs of each style, making them the de facto first commercial runs of 3-D-printed shoes. It's stupid to 3-D print an entire shoe.
