Wearing a designated pair of shoes while inside the home (slippers work great for this) is a great way to keep your carpet looking clean for a longer period of time, while maintaining a healthier living environment. This helps to keep the outdoors where it belongs and offers a better alternative to bare feet since your skin naturally releases moisture in the form of oil and sweat that can collect in your carpet and attract soil. The key to this is to avoid wearing the same shoes outdoors as that would defeat the purpose. 😉
