How often do you look at or think about the soles of your shoes?

You change into clean clothes every day, but when you change your shoes, the soles still carry dirt and bacteria.

The 421,000 bacteria on each shoe sole (according to a University of Arizona study) continue to feed happily off the plant and food debris that have collected on the bottoms of your shoes.

Viruses on Shoes

90% of these bacteria will transfer from your shoes onto clean tile floors.

Carpet is even worse! Organisms can survive longer in carpet and will continue to build up, along with mold, over time.

Dr. Charles Gerba, professor of microbiology and environmental sciences at the University of Arizona, studied the bacteria on the bottom of shoes and the massive amount that we track into our homes. Gerba credits this abundance to everything from pet waste and bird droppings to toilet splashes from public restrooms.

Common bacteria that are transferred from shoe to floor include E. coli, a source of urinary tract infections and diarrhea, and others that can cause pneumonia and respiratory tract infections.

A 2017 study by the University of Houston showed that more than 26 percent of shoes examined tested positive for C. diff, which causes a potentially deadly super diarrhea.

Shoe Bacteria

Even the soles of non-skid socks issued in hospitals are breeding grounds for disease-causing bacteria. Samples analyzed from slippers indicated a spread of harmful bacteria from floor to bed linen—methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile and multidrug-resistant Gram-negative bacteria, plus other pathogens (Rashid et al 2018).

If you’re not going to remove your shoes when you get home—or if you just want to avoid tracking harmful germs into your office, hotel room, gym, etc.—give the soles of your shoes 1-2 sprays of PlaneAire: the potent, all-natural surface sanitizer that’s made from 100% pure certified organic essential oils and a powerful blend of organic fruit acids.

PlaneAire’s proprietary formulation of organic fruit acids and essential oils was selected after testing 11 formulations at EMSL, optimized for antibacterial effectiveness. The antibacterial efficacy of 99.99% was demonstrated in the test method AOAC 961.02 on pathogenic bacteria: MRSA, Salmonella, Pseudomonas and Staphylococcus.
