Yes, we know. You didn't blow your rent money on an amazing pair of Louboutin pumps just so you could stare at them while you walk around barefoot.

But according to a new study, taking off your shoes when inside is healthier than leaving them on, as reported by The Daily Express.

Researchers from the University of Arizona, who have reported their findings in the Environmental Science and Technology journal, determined that 60 percent of dust comes from outside and is most commonly brought inside via the soles of our shoes, according to the paper.

(Yes, even those divine red Louboutin bottoms.)

And while dust may sound like something you can live with, the study reportedly found that shoes can track in dangerous poisons and pollutants such as arsenic and lead, posing a significant risk to children and pets.

So maybe it's time to turn your entryway into a makeshift shoe closet. After all, there's a lot we'd do for our Jimmy Choo and Manolo Blahnik heels, but making our kiddies or kitties sick just isn't one of them.
