Our first house had pine floors upstairs that were painted. We repainted them with just regular floor paint. They were pretty old ( the house was built around 1900), and kind of beat up, so if you were in your stocking feet, you might get a splinter on occasion. I love the look of a painted but distressed wood floor. I think that would be a practical solution that would be easier to maintain then a plain white painted floor. Or, maybe even a white washed look. That would still be more forgiving than plain white.

My sister has painted floors. they are white. They painted pine with a porch floor paint. She likes the ease of a wood floor but the white she has said many times was the wrong color. It shows every speck of dirt. every hair, every crumb.
She's said many times if she had to do it again she'd just as soon paint them another color or do a pattern.
