If you've been nursing for more than a year, you already know what twelve-hour shifts do to your feet. What's talked about less, but affects a significant number of healthcare workers, is what those same shifts do to the skin and nails over time: fungal infections that develop quietly under closed-toe nursing shoes, yellow thickening at the nail edges, and athlete's foot that seems to come back the moment it clears.
This article is for nurses, paramedics, allied health professionals, and anyone whose work keeps them on their feet in closed footwear for extended periods.
The Nurse Foot Health Reality
Eight to twelve hours on your feet during a shift is standard, not exceptional. Closed-toe shoes are non-negotiable; clinical environments require it for safety. The result is a foot environment that is under prolonged mechanical stress, enclosed in footwear for most of the working day, and often insufficiently dried and aired between consecutive shifts.
Why Nurses Develop Foot Conditions at Higher Rates
- Prolonged enclosed shoe wear: The interior of a closed shoe worn for twelve hours becomes warm and moist, the primary environmental requirement for dermatophyte fungi to thrive.
- Standing time and foot mechanics: Extended standing increases sweating on the sole and creates friction points that compromise the skin barrier.
- Floor exposure: Shared locker room floors, changing rooms, and shower facilities represent the same shared barefoot exposure environment as any communal facility.
- Compound exposure over time: Many consecutive shifts over months and years create cumulative risk.
The Three Conditions Nurses Get Most
Plantar Fasciitis
Inflammation of the connective tissue band on the sole of the foot; presents as sharp heel pain, particularly with the first steps after rest. The right nursing shoe with appropriate arch support is the most important intervention.
Athlete's Foot (Tinea Pedis)
Extremely common in the nursing population because of the closed, warm, moist shoe environment. Left untreated, dermatophyte fungi can progress to the toenails, where they become considerably harder to address.
Toenail Fungus (Onychomycosis)
Disproportionately common in nursing. Presents as yellowing, thickening, crumbling, or lifting of the nail, changes that often develop gradually. Nail fungus caught early is considerably more responsive to daily topical treatment than an infection that has progressed to the nail matrix.
The 60-Second Post-Shift Routine
- Remove shoes and socks as soon as you're in the changing room or at home.
- Clean and dry your feet thoroughly, particularly between each toe.
- Spray Sole Shield on the soles of your feet, between your toes, and on the lower foot. Let it dry for about 60 seconds.
- Spray Sole Shield inside both nursing shoes. Set them aside unzipped in open air.
- Put on clean socks or open footwear. Your feet need air time between shifts.
If You're Already Noticing Nail Changes
EZ Clear Nails is an aqueous iodine nail spray for daily use on the nail surface, edges, and surrounding skin. Spray onto clean, dry nails after applying Sole Shield to the feet, and let dry before putting on socks. Consistent daily use over several months as the nail grows out is the approach with the most practical support.
Shoe Rotation: The One Practical Change That Makes a Real Difference
Own two pairs of nursing shoes and alternate between them. When you finish a shift, the shoes you wore come off and get Sole Shield sprayed inside them. They sit unzipped in open air for at least twenty-four hours while you wear the other pair. Both pairs stay drier over the course of the week. The fungal burden in the shoe interior is lower, and so is the end-of-shift odor that has some nurses using body deodorant on their feet.
Frequently Asked Questions
Do nurses get toenail fungus more often?
Healthcare workers in clinical roles that require prolonged closed-shoe wear have a meaningfully elevated occupational risk for both athlete's foot and toenail fungus compared to the general population.
What is the best foot care routine for nurses?
After each shift: dry feet thoroughly, spray Sole Shield on soles and between toes, spray inside nursing shoes, and change into clean open footwear. If nail changes are already present, add EZ Clear Nails to the routine. Rotate between two pairs of shoes so each pair fully dries between wears.
How do I prevent athlete's foot from nursing shifts?
Dry your feet completely after showering. Spray Sole Shield on feet and inside nursing shoes after each shift. Rotate between two pairs of shoes. Wear flip flops in shared changing room and shower facilities.
The Two-Product Routine Nurses Use for Their Own Feet
Sole Shield, spray on feet after every shift. Spray inside nursing shoes.
EZ Clear Nails, for nurses who've noticed nail changes. Daily spray on clean dry nails, every day, consistently.

Common Mistakes Nurses Make With Foot Care
Even nurses who are diligent about their foot health tend to repeat a few patterns that undermine their results. These are worth knowing before starting any new routine.
Only treating one foot
Dermatophyte fungi spread easily between feet, and typically both feet share the same shoe and sock environment throughout the entire shift. If one foot shows nail changes or signs of athlete's foot, both feet should be included in the routine consistently, even when the other foot appears unaffected. Fungi do not stay on one side.
Stopping the routine when symptoms improve
This is probably the most common reason athlete's foot recurs. Surface improvement can happen within days, but the fungal environment inside the shoe has not changed. Maintaining the post-shift spray routine beyond visible symptom resolution is the step most people skip, and the reason many nurses find themselves dealing with the same issue months later. The routine only works if it keeps running.
Not drying between the toes
The interdigital spaces, particularly between the fourth and fifth toes, are the most common site for early athlete's foot to develop. They're also the spots most likely to retain moisture after showering or washing. Taking an extra twenty seconds to dry each interdigital space individually makes a measurable difference to skin condition in that area over time. A dedicated small towel kept for foot drying makes this easier to do consistently.
Treating the feet but not the shoes
If the shoe interior is not addressed, re-exposure from the shoe itself is almost inevitable. Sole Shield is designed to be used both on the feet and sprayed directly inside each shoe after every shift. The shoe is part of the environment being managed, not a passive bystander in the process.
The 90-Day Protocol: Soak, Spray, Repeat
For nurses already dealing with nail changes or recurrent athlete's foot, a more structured approach produces better results than occasional use. IodinePure's 90-day protocol is built around two complementary habits:
- Spray twice daily, morning and evening, on clean dry skin and nails. This is the daily maintenance step that supports consistent product contact with the nail surface throughout the growth cycle.
- Foot soak 3 to 4 times per week, a 5-to-7-minute soak in the EZ Clear Nails solution, using the soak tray included in your kit, softens the nail plate slightly and supports better surface contact between the formula and the nail. Dry thoroughly before spraying and allow to air dry fully before putting on socks.
The rhythm is straightforward: soak, spray, repeat. 3 to 4 times per week for the soak, twice a day for the spray. The 90-day timeframe is practical rather than arbitrary; toenails grow approximately three millimetres per month, and the protocol is designed to work with the nail's natural growth cycle. Visible improvement comes from healthy nail growing in to replace the affected nail, which takes sustained effort over months, not weeks.
For Sole Shield, the same consistency principle applies: apply after every shift without skipping, even on days when feet feel completely fine. The goal is maintaining an environment that doesn't support recurrence, not just reacting when symptoms return.
Sock Choice Matters More Than Most Nurses Realise
Compression nursing socks provide genuine circulatory and fatigue benefits over long shifts, but the material composition also matters significantly for foot health. Socks with a high moisture-wicking synthetic content, like polyester, nylon, or merino wool blends, move sweat away from the skin surface and reduce the sustained moisture contact that contributes to maceration and fungal risk. All-cotton socks absorb sweat but hold it against the skin, which is the opposite of what you want inside a nursing shoe during a twelve-hour shift. If you are managing athlete's foot or nail changes, switching to a moisture-wicking sock is one of the most straightforward upgrades available; it costs very little and improves the foot environment inside the shoe for every hour of every shift.
