Travelling Toxins: The first proof that pesticides can be tracked into a home on shoes was released by the EPA. According to the study, pesticides such as 2, 4-D, can remain on a lawn for up to a week after application.
Both animals as well as humans can track these chemicals into a home. Another study showed that 98 percent of all lead dust found within a home is tracked in from the outside.
Germs: Those that live in heavily populated urban areas should beware of things that they pick up from sidewalks, escalators and stairways. It is possible to bring in everything from animal waste to human body fluids on the soles of your shoes.
Comfort: Depending on your shoes and how much standing or walking you do daily, your feet need a rest at the end of the day. Taking off your shoes and slipping into a comfy pair of house slippers lets your feet breathe and allows you to stretch and massage your tired toes.
Dirt: Who wants a house full of dirt? Although the invention of paved roads did away with the traditional boot scrapers at the front and back doors of homes, dirt still finds its way into the crevices of shoes and into your home.
