The no-backwards device is the second essential element for the working of Wokenrol skates.
This time, this element plays a part on comfort.
By prohibiting displacements backwards, it increases a lot running in straight line.

A simple push on a foot is enough to go of three meters or more.

Moreover, it is enough to push each foot directly backwards without having to balance itself from right to left as with traditional rollers.
It is now possible to circulate on a pavement, along a straight line, without occupying all the width of this pavement.
And of course, the no-backwards device allows to go up slopes without tiring.
Because, if braking makes it possible to go down slopes, you will need to go up then.
