The evidence is mixed but pointed. Researchers have studied shoe soles as vectors for infectious disease without landing on a single proven decontamination strategy, and one ICU study found that shoe covers did not improve infection rates, mortality, or length of stay. But a 2022 study epidemiologically linked pathogens on healthcare workers' shoes to patient infections, which makes the soles a plausible route of transmission. Bottom line: cleaning your shoes is a low-cost way to lower the odds you spread something.
Disinfect Inside and Out
Your feet carry roughly 250,000 sweat glands and can put out close to a pint of sweat a day. That fluid soaks into your socks and the bed of your shoe, where it feeds bacteria and fungus. The inside matters as much as the sole.
The best routine is the one you will actually repeat. Some facilities install UV-C floor-sanitizing platforms near nursing stations. You stand on them for about 8 seconds and they destroy most pathogens on the soles. If your unit moves a lot of staff between rooms, that is worth raising with your manager.
At home, pick a method and stick with it:
- Disinfectant sprays or wipes. Use a fresh wipe per shoe and keep the surface wet for the full contact time on the label.
- Hydrogen peroxide. A 3% solution lifts visible stains. Mixed with two parts baking soda, it makes a disinfecting paste for uppers and soles. Apply two layers, then rinse or let it dry and wipe off.
- Rubbing alcohol for leather. It kills germs and is gentle on the material. Wipe with three parts alcohol to one part water, or spray and let dry.
- Bleach for white canvas only. One part bleach to five parts water works, but it will strip color from anything else.
Kill the Odor Too
Odor is not just unpleasant. It signals fungal or bacterial growth. Baking soda and white vinegar will not kill every virus, but they slow fungal growth. Sprinkle baking soda inside and out, spray with vinegar, let it sit about 12 hours, then shake out the baking soda.
For a hands-off option, ozone-based shoe sanitizers seal the shoe in a chamber and run a cycle that kills bacteria and clears odor in roughly 90 minutes, often with mild heat to dry out sweat. Smaller UV-C sanitizer boxes and in-shoe UV-C inserts do the same job at home in 5 to 15 minutes, though most only fit one shoe at a time. Any of these handles the inside of the shoe, which sprays and wipes tend to miss.
Frequently Asked Questions
Do dirty shoe soles actually spread infection in hospitals?
The evidence is suggestive rather than settled. A 2022 study in the Journal of Hospital Infection matched Clostridioides difficile strains on healthcare workers' shoe soles to infected patients using whole-genome sequencing, making the soles a plausible route of transmission. Floors and shoes are low-touch surfaces, so the risk is lower than for hands, but cleaning your shoes is a cheap way to lower the odds.
How often should nurses clean their work shoes?
Wipe down the soles after each shift, especially after caring for patients on isolation precautions, and do a deeper clean of the uppers and insides weekly. The best schedule is the one you will actually keep.
What is the best way to disinfect nursing shoes?
Match the method to the material: disinfectant wipes or sprays kept wet for the full label contact time, a 3% hydrogen peroxide and baking soda paste for stains, three parts rubbing alcohol to one part water for leather, and a one to five bleach solution for white canvas only.
How do I get the smell out of nursing shoes?
Odor signals fungal or bacterial growth. Sprinkle baking soda inside and out, spray with white vinegar, let it sit about 12 hours, then shake it out. Ozone or UV-C sanitizer boxes treat the inside of the shoe that sprays and wipes usually miss.
Should I wear my work shoes home?
It is better not to. Your soles carry whatever was on the unit floor into your car and home. Keep a dedicated pair for work, clean them regularly, and change before you leave when you can.
