These sneakers are made out of living cells. Designed by Shamees Aden, the prototypes, dubbed “Protocells,” are designed to repair themselves: if you scuff your shoes after a run, just dump them in a container of “protocell liquid,” and the cells will heal. Aden says they could be a reality by 2050.

They’d also respond to the terrain while you run. “The cells have the capability to inflate and deflate and to respond to pressure,” she said. “As you’re running on different grounds and textures it’s able to inflate or deflate depending on the pressure you put onto it and could help support you as a runner.”

They’re also terrifying looking. I can’t imagine anyone besides self-identified “futurists” would be willing to wear something that looks more like a barnacle-laden undersea creature than it does like a shoe, but hey, we can dream.
