German skate shop, Emil Boards, have introduced a line of square boards! They were inspired by Back to the Future and thought, if they can have them in fake 2010, why can't we have them now!?
These boards are totally basic and are have a square shape, no convex, no concarve, no concave, no rocker, no camber, and of course no batteries."
You are meant to "surf the sidewalk" with these, and the guys in the video I attached did a pretty good job!
