Work shoes get gross.
That isn’t a character flaw.
A nurse can spend twelve hours walking, standing and sweating inside the same pair, then do it again the next day.
The combination of:
- Heat
- Moisture
- Sweat
- Foam
- Fabric lining
- Repeated wear
creates exactly the environment where shoe odor thrives.
The best strategy is not simply covering the smell with fragrance.
It is:
- Let shoes dry fully.
- Rotate pairs when possible.
- Use a deodorizer that addresses odor rather than just masking it.
- Clean the upper and outsole according to the manufacturer’s instructions.
- Replace insoles when they become permanently saturated or compressed.
Here are the shoe-care products we’d start with.

For heavily used nursing shoes, we’d start with FunkAway Odor Eliminating Spray.
Current retail listings position it specifically for:
- Shoes
- Work boots
- Sports gear
- Other items that cannot be easily washed
That makes more sense for hospital shoes than a generic room spray.
Why we like it
- Made specifically for footwear and gear
- Easy to apply between shifts
- Inexpensive
- Useful for sneakers, clogs and work shoes
Best for
Nurses whose shoes smell noticeably after repeated long shifts.

1. Arm & Hammer Gear & Shoe Refresher — Best Budget Spray
Arm & Hammer’s current Gear & Shoe Refresher uses baking soda and odor-neutralizing ingredients and is designed for footwear and sports gear that cannot easily be washed.
Current retail pricing can be under $10.
Why we like it
- Cheap
- Easy to find
- Shoe-specific
- Useful for lockers and gym bags too
Best for
Anyone who wants a simple spray without spending much.

2. Sof Sole Sneaker Balls — Best Locker and Work-Bag Option
Sneaker Balls are tiny twist-open deodorizers designed to sit inside:
- Shoes
- Gym bags
- Lockers
- Small storage spaces
They are useful when you don’t want to spray liquid into the shoe.
Why we like them
- Small
- Cheap
- Easy to keep in a locker
- No mess
Downside
These are more about odor control and freshness than deep cleaning.
If the shoe lining itself is saturated with sweat, a ball won’t magically restore it.

3. Bamboo Charcoal Inserts — Best Fragrance-Free Option
Some people dislike scented sprays.
Bamboo-charcoal shoe inserts are designed to absorb moisture and odor without adding perfume.
Current products such as Moso Natural shoe inserts use bamboo charcoal rather than fragrance.
Why we like them
- Fragrance-free
- Reusable
- No liquid
- Can sit inside shoes between shifts
Best for
Nurses who are sensitive to scented products or simply don’t want perfumed work shoes.

4. Replace the Insole When Necessary
Sometimes the odor isn’t primarily in the upper.
It’s in the footbed.
If you have removable insoles and they:
- Smell immediately after drying
- Stay compressed
- Look permanently dirty
- No longer provide cushioning
replacing them may make more sense than spraying indefinitely.
Important
Replace the original insole with something that fits the shoe’s volume.
A thicker aftermarket insole can make the shoe too tight.
5. Shoe Rotation — Best Prevention Strategy
This is the single most useful habit on the page.
If you can afford two pairs of work shoes, alternate them.
That gives each pair more time to:
- Dry
- Air out
- Recover
- Release trapped moisture
Wearing the same damp shoe again the next morning is an excellent recipe for odor.
We’ll cover second-pair strategy separately in Best Backup/Second Pair Shoe Picks.
Why Work Shoes Smell
Sweat itself is not the whole problem.
Odor develops when moisture, heat and microorganisms interact inside the shoe.
Running and work-shoe deodorizer testing published in 2026 consistently emphasizes moisture and odor-producing bacteria as central reasons shoe odor becomes persistent.
That’s why simply adding fragrance often provides only temporary improvement.
Air Shoes Out After Every Shift
Don’t immediately seal damp shoes inside:
- A plastic bag
- Closed locker
- Car trunk
- Suitcase
when you have another option.
Remove them.
Open the tongue.
Loosen the laces.
Take out removable insoles if necessary.
Let air move through them.
Don’t Leave Work Shoes in a Hot Car Forever
A hot car may seem like a drying chamber.
Unfortunately, repeated heat can be rough on:
- Adhesives
- Foam
- Leather
- Synthetic materials
Airflow at normal temperatures is a better long-term strategy.
Washable Shoes: Follow the Label
Do not throw every sneaker into a washing machine.
Some manufacturers allow it.
Others don’t.
Machine washing can affect:
- Glue
- Foam
- Shape
- Leather
- Water-resistant treatments
Use the manufacturer’s instructions.
Cleaning Leather Work Shoes
For leather shoes such as HOKA Bondi SR, Dansko clogs or leather walking shoes:
- Wipe loose dirt.
- Use a damp cloth or manufacturer-approved cleaner.
- Clean the tread separately.
- Let the shoes dry naturally.
- Avoid soaking leather.
Clean the Outsole Too
Hospital floors are not clean environments.
Check the tread for:
- Debris
- Hair
- Dirt
- Sticky residue
A clogged slip-resistant outsole may provide less traction than a clean one.
Socks Matter
Moisture-wicking socks can reduce how much moisture remains against the foot.
If your feet sweat heavily, try:
- Synthetic performance socks
- Merino blends
- Changing socks during especially long shifts
Can You Use Baking Soda in Shoes?
People have used baking soda for decades.
It can help with odor.
The downside is mess.
Loose powder can remain inside the shoe and transfer onto socks.
A contained product or shoe-specific spray is easier for everyday use.
Can You Use Disinfectant Spray Inside Shoes?
Only if the product is actually intended for that use.
Some current shoe products are specifically marketed as shoe disinfectants and deodorizers.
Do not randomly spray harsh household disinfectants into footwear.
They may:
- Damage materials
- Irritate skin
- Leave residue
Follow the product label.
When Is It Time to Replace the Shoe?
No deodorizer can rescue a shoe that has reached the end of its useful life.
Consider replacement if:
- Foam is flattened
- Tread is worn smooth
- Upper structure has collapsed
- Odor immediately returns
- Interior padding is breaking down
- New foot pain develops
Frequently Asked Questions
What is the best shoe deodorizer for nursing shoes?
FunkAway is our overall spray pick, while Sof Sole Sneaker Balls are useful for lockers and charcoal inserts are good for fragrance-free odor control.
Do shoe deodorizer balls actually work?
They can help control mild odor and keep stored shoes fresher, but they won’t fix deeply saturated shoe linings.
Is baking soda safe for shoes?
It can help with odor, but loose powder can become messy. A product designed specifically for shoes is easier.
Should I wash nursing shoes?
Only if the shoe manufacturer says the material can be washed that way.
How do I stop work shoes from smelling?
The best combination is rotation, complete drying, clean socks and a shoe-specific odor-control product.
Our Verdict
Our first choice is FunkAway for shoes that already smell.
For inexpensive daily upkeep, Arm & Hammer Gear & Shoe Refresher is easy to recommend.
For lockers, Sneaker Balls are convenient.
But the most effective long-term strategy isn’t a spray at all:
own two pairs and let each pair dry completely between shifts whenever possible.
