Don't do it much but the best I've been able to do was with a good amount of background noise from a group of starlings on a windy day after a rain. I was also wearing moccasins.

I've read that animals communicate through ground vibration. Never heard that when a deer stomps it's hoof it was also sending a signal until lately, I thought it was just leaving a scent, so learning to walk lightly is a desired trait. Never putting weight on your front foot until it's all the way down is how I've heard it is done.
