If you’re a big fan of walking around barefoot, you may want to re-consider. Your skin naturally releases moisture which comes out as oils or sweats, which when you walk around barefoot transfers from your foot to the surface of your carpet fibers. This moisture attracts dust, dirt, and dander and over time it can build up and become noticeable. Wearing your shoes indoors isn’t the answer as that can track in far more contaminants. The best option is to wear socks inside or to have special indoor-only slippers by your front door to put on when you make the transition from outside to inside your home.
