Did you know Segway is making a pair of self-balancing roller shoes? It is! The company has been tinkering with all sorts of new form factors since it was acquired by Ninebot in 2015, from half-sized Segways to kick scooters. Next up: inline… shoe… platform things.

Called the Segway Drift W1s, they sorta look like what would happen if you took a hoverboard (as in the trendy 2016 hoverboard-that-doesnt-actually-hover “hover”board, not Marty McFly’s hoverboard), split it in two, and plopped one half under each foot.
