The shape makes sense in order to minimize weight and have max stiffness and strength - and with some rad looking lines also
Reminds me slightly of the around 7 year old pic (also from France) with a rider having two bindings on a stick, and nothing but that, as the board.
Can anyone find this picture again?
But I like it seems to have a tad of volume so you can ride it strapless, and (jump)switch feet, and apparently nose scoop so should be okay to start
As opposed to a flat small skimboard which is crazy tough to start, or gives an odd leg angle
