How to stop footstep sounds playing when jumping?

I currently have this:

But it seems way to complex to me to add a reference to each thing I want to have footstep sounds on.

I know I can add a physics material to it, but then when I jump, it still makes the footstep sounds.

So my question is, how can I stop the footstep sounds from playing when the player is in the air?

I don’t have a jump animation, so that doesn’t work.
