How to Clean Shoe Insoles
If your shoes still smell even after you’ve cleaned the outside, the insoles are often the culprit.
They sit directly under your feet, so they absorb sweat, moisture and everyday dirt. Luckily, most removable insoles can be cleaned at home without putting them anywhere near a washing machine.
The safest approach is usually simple: mild soap, a damp cloth and plenty of time to air dry.
How to Clean Shoe Insoles
First, remove the insoles from your shoes.
Brush off any loose dirt or debris using a soft brush or an old toothbrush.
Then:
- Mix a small amount of mild soap with lukewarm water.
- Dip a cloth, sponge or soft brush into the mixture.
- Gently clean both sides of the insole, paying extra attention to the heel and forefoot.
- Wipe away any remaining soap with a clean damp cloth.
- Leave the insoles to air dry completely before putting them back into your shoes.
Avoid soaking them unless the manufacturer specifically says it is safe.
And definitely avoid radiators, tumble dryers or hairdryers. Too much heat can warp foam and weaken adhesives.
How Do You Get Smells Out of Insoles?
If the insoles are clean but still a bit whiffy, baking soda is one of the easiest options.
Once the insoles are completely dry, sprinkle a light layer over them and leave it overnight.
Brush or shake the powder off the following morning before putting them back into your shoes.
Simply taking your insoles out after wearing your shoes and allowing them to air overnight can also make a big difference.
Can You Wash Foam Insoles?
Usually, yes, but gently.
Most foam or fabric-topped insoles can be cleaned using a damp cloth or soft brush with mild soapy water.
Try not to completely saturate the foam. It can hold onto water for a long time and may lose its shape if heavily soaked.
Let them dry naturally and do not put them back into the shoes until they are completely dry.
How to Clean Gel Insoles
Gel insoles are best wiped rather than scrubbed aggressively.
Use a soft cloth with lukewarm water and a small amount of mild soap, paying attention to grooves where dirt tends to collect.
Avoid abrasive brushes or cleaners that could damage the surface.
Leave them flat to air dry afterwards.
How to Clean Leather Insoles
Leather needs a little more care.
Use a barely damp cloth with a very small amount of mild soap and wipe the surface gently.
Do not soak leather insoles.
Once clean, leave them to dry naturally at room temperature and away from direct heat or strong sunlight.
What About Wool or Felt Insoles?
Thicker winter insoles can take a long time to dry, so spot cleaning is normally better than soaking.
Brush off dried mud and debris first, then use a damp cloth and mild soapy water on any dirty areas.
Leave them somewhere well ventilated until completely dry.
Can You Put Insoles in the Washing Machine?
For most insoles, we wouldn’t.
Machine washing can distort foam, damage glued layers and affect the overall shape.
If the manufacturer specifically states that the insole is machine washable, follow their instructions. Otherwise, hand cleaning is the safer option.
How Often Should You Clean Shoe Insoles?
There is no exact schedule.
Someone wearing the same shoes every day will probably need to clean their insoles more often than someone wearing them once or twice a week.
Sports and gym shoes may also need more regular attention because they tend to get damp more frequently.
A good rule is simply to clean them when they start to smell, look dirty or stay damp after use.
When Should You Replace Insoles Instead?
Cleaning will not revive an insole forever.
It may be time for a replacement if:
- the cushioning has become permanently flat
- the material is cracked or peeling
- the top layer has worn through
- they remain strongly scented even after cleaning
- they no longer feel comfortable inside the shoe
If the shoe itself is still in good condition, replacing the insole can sometimes give it a useful second life.
Simple Ways to Keep Insoles Fresher
A few habits can reduce how often you need to deep clean them:
- let shoes air after wearing them
- remove damp insoles overnight
- rotate between pairs where possible
- wear fresh socks
- avoid storing damp shoes in closed bags or cupboards
- clean mud and moisture off before putting shoes away
Nothing fancy required.
The Bottom Line
Most shoe insoles can be cleaned easily using lukewarm water, mild soap and a little patience.
Avoid soaking them unnecessarily and always let them air dry fully.
For lingering smells, baking soda and regular airing can help, but if an insole is badly worn, cracked or permanently flattened, replacement is probably the better option.
