How to make foot to leave a print on snow?

Hi I was wondering how to make foot prints on snow, when the player is walking.

As far as I know I could use decal system to draw textures on foot locations, but what would be the best way so the foot print would look smooth with the terrain, so it wouldnt look like texture floating, in case of having uneven terrain.

Im going to check how people have implemented skidmarks in their cars, but i believe there could be a betterway.

Has anyone implemented t$$anonymous$$s before, or have an idea that could lead me into right direction?

Thank you
