ślad stopy inglês:

Tom believes he has a very low carbon footprint.

All visitors leave a footprint

We left footprints in the snow when we walked across the garden.

I took a photo of this strange footprints.

His carbon footprint is huge – he’s always flying.

There's only one creature capable of leaving a footprint that size.

Judging by the size of this footprint, I'd say the perp is about six feet tall.
