Dryers vs deodorizers for boot smell
A deodorizer treats the output. A dryer removes the input. We publish this on a page that earns from both, because the arithmetic is not close.

If the boots are damp between wears, buy a dryer. If they are dry and still smell, buy a deodorizer. That is the split, and for most people with a smell problem the honest answer is the first one - which is inconvenient for us, because deodorizers are the cheaper impulse purchase and we earn on both.
The two products are not doing the same job
Foot odor is bacteria on the skin feeding on sweat, thriving in warmth, darkness and moisture. Of those four conditions - skin, sweat, darkness, moisture - moisture is the only one you can control between wears. A boot dryer removes it. A deodorizer does not touch it; it treats what the bacteria have already produced, or adds a scent on top.
| Boot dryer | Deodorizer | |
|---|---|---|
| Targets | The condition (moisture) | The output (odor compounds) |
| Effect over time | Problem stops recurring | Repeats every wear |
| Cost shape | One purchase, then pennies of power | Consumable, bought again and again |
| Also fixes | Wet feet, leather damage, slow drying | Nothing else |
| Works on a wet boot | That is the point | No - most are worse on wet boots |
The running cost, shown
The formula is watts ÷ 1000 × hours × $/kWh, using the EIA average residential rate of 18.34 cents per kilowatt-hour that we use across this site.
A 36-watt convection dryer running 8 hours a night: 36 ÷ 1000 × 8 × 0.1834 = about 5.3 cents a night. Over a 90-night season that is about $4.75 of electricity. That is the entire ongoing cost of removing the condition the bacteria depend on, every night, all winter.
A can of deodorizer used through the same season is a recurring purchase that leaves the boot exactly as damp as it found it. You can run the numbers for your own electricity rate and your own dryer in the running-cost calculator.
When the deodorizer is genuinely the right buy
Three cases, and they are real:
- The boots are already dry and still smell. The bacteria are established in the lining. Removing moisture stops it getting worse but does not remove what is there - a carbon pad or a treatment does.
- You cannot leave anything plugged in. Shared accommodation, a locker, a truck. A pad or powder needs no power and no space.
- It is a gym bag, not a boot. Short-term storage of already-dry footwear is exactly what a scented insert is for.
The combination, if you want the complete answer
Dryer every night, insoles out, and a drying powder once or twice a week. The dryer stops the condition recurring, the removed insole gets air to the wettest part, and the powder handles what is already in the lining. Most people never need more than this.
What we would buy for this
Chosen from the same registry as our roundups, on published specifications rather than on testing we have not done.
PEET
PEET Original 2-Shoe Dryer
The convection dryer the rest of the category gets measured against: 36 watts, no fan, no noise, and a 25-year warranty behind it.
Skip it if: You need boots dry in two hours. PEET's own FAQ puts non-fan models at 4 to 8 hours.

Dr. Scholl's
Dr. Scholl's Odor-X Odor Fighting Spray Powder
A powder rather than a liquid, which matters: powder absorbs the moisture the bacteria need instead of adding more.
Skip it if: You want the smell gone tonight - powder is a prevention product, not a rescue.

Zorpads
Zorpads Shoe Inserts
Thin activated-carbon pads that stick to the footbed and adsorb odor compounds instead of covering them with perfume.
Skip it if: The boot is wet. Carbon that is saturated with water cannot adsorb anything else.

Frequently asked
Do boot dryers get rid of the smell?
Indirectly, and it is the most effective thing you can buy for the problem. Odor comes from bacteria feeding on sweat in a warm, damp, dark boot. A dryer removes the moisture, which is the one variable in that list you can control between wears.
How much does it cost to run a boot dryer all winter?
For a 36-watt convection dryer at 8 hours a night and the EIA average of 18.34 cents per kWh, about 5.3 cents a night, or roughly $4.75 across a 90-night season. The sum is watts / 1000 x hours x price per kWh.
Is a deodorizer enough on its own?
Only if the boots are genuinely dry between wears. If they are not, you are treating the output while the cause runs continuously, and the smell returns every time.
Can I use a deodorizer and a dryer together?
Yes, and that is the complete answer for an established smell. Dry the boots, pull the insoles, and use a drying powder or carbon pad on what is already in the lining. Just do not spray a liquid into a boot before drying it.
