How to Wash Shoes Insoles (The Right Way)
The short answer is yes, you should wash your insoles, and yes, it’s easy. Most insoles just need a quick hand wash with mild soap and a thorough air dry. This simple habit removes odor-causing bacteria, extends the life of your shoes, and makes every step feel fresher.
Check the Material First
Before you get anything wet, look at what your insole is made of. This determines the entire cleaning method.
- Foam and EVA: These are the most common. They are safe to wash with water and mild soap.
- Leather: Never soak leather. Use a damp cloth and saddle soap to spot clean.
- Suede: Water ruins suede. Use a suede brush to lift dirt instead.
- Cork: Cork is sensitive to moisture. Wipe with a barely damp cloth and dry flat.
- Gel: Gel insoles are usually fine with a quick rinse, but avoid harsh scrubbing.
If you are unsure, check the tag or the manufacturer’s website. When in doubt, start with the gentlest method—a dry brush or a damp cloth—before moving to a full wash.
The Hand-Washing Method for Most Insoles
For foam, EVA, and fabric insoles, hand washing is the safest and most effective method. It is gentle on the glue and the materials.
Fill a sink or basin with lukewarm water. Add a small drop of mild dish soap or a bit of laundry detergent. You do not need much—a little goes a long way.
Use a soft-bristled brush, like an old toothbrush, to gently scrub the surface. Focus on the heel area and the ball of the foot, where sweat and grime build up the most. Rinse thoroughly with clean water until all the soap is gone. Squeeze out excess water gently. Do not twist or wring the insole, as this can damage its shape.
Machine Washing: When It’s Okay
Some insoles can handle the washing machine, but you need to be careful. Check the care label first. If it says “machine washable,” use a cold, gentle cycle.
Always put your insoles inside a mesh laundry bag. This protects them from getting caught or bent in the drum. Wash them with a small load of towels to balance the machine. Use a mild detergent and skip the fabric softener, as it can break down the foam.
Never put insoles in the dryer. The heat will warp them and melt the glue that holds them together. Always air dry.
The Right Way to Dry Insoles
Drying is just as important as washing. Rushing this step can ruin your insoles and create a mildew problem.
Never use a dryer, a radiator, or direct sunlight. High heat will cause the insoles to shrink, curl, or peel apart. Instead, pat them dry with a clean towel to remove excess moisture. Then, place them flat on a drying rack or a towel in a well-ventilated room.
It can take 12 to 24 hours for insoles to dry completely. Make sure they are fully dry before putting them back in your shoes. A damp insole trapped in a dark shoe is a breeding ground for bacteria and fungus.
How to Deodorize Stubborn Smells
If washing alone does not kill the odor, you need to neutralize the bacteria causing it. A simple soak can do the trick.
Mix a solution of one part white vinegar to three parts water. Soak the insoles for 15 to 30 minutes. Vinegar is a natural deodorizer and kills bacteria without leaving a strong smell once dry. Rinse them with plain water afterward.
Another option is baking soda. Sprinkle a generous layer over the insoles and let them sit for a few hours. The baking soda absorbs odors and moisture. Brush it off completely before washing or wearing.
When to Replace Instead of Wash
Washing can only do so much. Insoles have a lifespan, just like shoes. If your insoles have lost their cushioning, are visibly cracked, or have a permanent smell that will not go away, it is time to replace them.
Most standard insoles last about six months to a year with regular wear. If you run or exercise in your shoes, you may need to replace them more often. Washing a worn-out insole is a waste of time. A fresh pair will give you better support and comfort.
Frequently Asked Questions
Can I wash insoles in the washing machine?
Yes, only if the care label says it is safe. Use a cold, gentle cycle and place them in a mesh laundry bag. Never use a dryer. Air dry them flat instead.
How often should I wash my shoe insoles?
For everyday shoes, wash them once a month. If you sweat heavily or wear your shoes for intense activity, wash them every two weeks. You can also spot clean them weekly to control odor.
Will washing insoles ruin the glue?
Hand washing with lukewarm water and mild soap is safe. The problem is heat and harsh chemicals. Avoid hot water, bleach, and the dryer. These will break down the adhesive and cause the insole to separate.
Can I put wet insoles in the sun to dry?
No. Direct sunlight can warp the materials and cause them to shrink. Always dry insoles in a shaded, well-ventilated area at room temperature.
