indentation scuffs on floor

[mrorange1]

Hi all,
picture above is of my floor in one of my rooms. As you can see it has some indentations and looks worn. I'd like to know the best approach to covering such indentations and then I'd like to try and bring the floor back to life a little on a budget. Would i use a staining product on the floor and any suggestions for what to cover the indentations with to get it back to an even layer?
any ideas would be appreciated.
thanks.

Usually just left and treated as character on timber floors, but you can try a damp cloth and a domestic iron it often works on dents in furniture. Heat it like you were ironing crumpled denim.
