Shoes on or off inside the house???

I know this isnt pregnancy related but its something my fiance and I argue about all the time. He always wears his dirty shoes inside the house, and brings in grass, leaves, dirt and stuff. Hes always working on things outside, so hes always back and forth inside. we have wood floors so when its dirty I need to sweep and mop the floor. Do you guys take off your shoes in the house?? Or am i being a nag
