Collision for 3d fighting game

Hi !
Everything is in the title.
I have really no idea on how i can implement basic collision detection for a 3D fighting game like tekken.

My idea was to add some simple collision boxes in a rigged character. For example, add a collision box on the leg.
So, if my character make a kick, the box will follow the movement and collide with some other boxes.
But is this even possible ?

Or maybe a totally different approach is necessary ?
If you have any idea or please let me know.

I need something fast rather that something accurate.

Thank you in advance for any help.
Regards.
