This is an original ITF style kick...
...and is taught in some very traditional ITF based TKD schools. I can do it but rarely do because it is very awkward and quite easy to injure your big toe :sad10:
The jist of executing the techique properly is the kick is not delivered directly in front of you but at 30 to 45 degrees off to the side (ITF thinking again). So you would turn slightly away from your opponent (or board) and deliver the kick i.e., turn 30 degrees to your left to deliver a right leg kick. Anatomically your toes should be in a better position.
Try it and let us know what you think and then stop using it. It is slow and ineffective...
