I think you'll find that most of us here don't bother with footprints. I do check the ground before putting up my tent and remove sticks, rocks, etc.

Even when I had a tent with a super-lightweight silnylon floor, I didn't bother with a footprint. The floor took no harm either from the ground or from my dog's claws.

Generally, the floor is the least vulnerable part of the tent. However, I do recommend (from experience) that you not pitch the tent over a mouse hole!
