InsoleWars Troubleshooting Guides
Insole Problems & Fixes
Already have insoles and something isn’t right? Find your symptom, understand what’s causing it, and fix it. Most insole problems are mechanical and solvable without buying anything new.

Start With Your Symptom
Find what your insoles are doing, then go straight to the fix.
| Symptom | Most likely cause | Fix |
|---|---|---|
| Insole is too long for the shoe | Bought to shoe size, not insole size | Trimming safely → |
| Heel lifts when walking | Heel raised out of the counter | Stopping heel slip → |
| Squeaking with each step | Friction or trapped moisture | Stopping the squeak → |
| Insole slides forward | No adhesion, or wrong length | Securing the insole → |
| Edges curling or bunching | Trim error or moisture | Flattening edges → |
| New pain since fitting | Adjustment period, or a mismatch | Normal or not? → |
| Persistent smell | Moisture held in the foam | Clearing odour → |
Fit Problems
Most fit complaints come down to volume and length, not shoe size. These guides cover what to do once the insole is already in your hands.
Trim Guide
How to Trim Insoles
Trace, cut wide, test, trim again — plus the three mistakes that make an insole unusable.
Sizing Problem
Insole Too Short or Too Long
What to do when the insole doesn’t match the shoe, and when it can’t be salvaged.
Fit Adjustment
Can You Stack Two Insoles?
When doubling up works, when it causes heel slip, and what to do instead.
Wear Problem
Insole Edges Curling or Bunching
Why edges lift, how to flatten them, and the trim error that usually causes it.
Before You Troubleshoot
Some problems come from fitting or sizing in the first place. These basics guides cover the groundwork.
How to Measure a Shoe Insole
Length and width, so replacements actually match.
How to Put Insoles in Shoes
Correct positioning, and when to remove the original.
Can Insoles Make Shoes Smaller?
How added thickness changes internal volume.
Do Shoe Insoles Work?
What insoles can and can’t change inside a shoe.
Movement and Noise Problems
If the insole moves, so does your foot. These faults are mechanical and almost always fixable without replacing anything.
Fit Adjustment
Heel Slipping After Adding Insoles
Why insoles lift your heel out of the counter, and the lock-lacing technique that fixes most cases.
Troubleshooting
Why Insoles Squeak
Diagnose by where the noise comes from, four fixes, and how to tell when it isn’t the insole at all.
Troubleshooting
Insole Sliding Forward in the Shoe
Adhesion options, length checks, and why sock choice matters more than people expect.
Material Care
Why Insoles Smell
Where odour actually comes from, what clears it, and what makes it worse.
Comfort and Pain Problems
Some soreness in the first week is common. Pain that sharpens or persists is not, and is worth having assessed.
Comfort Guide
New Pain After Starting Insoles
What a normal adjustment period feels like, what isn’t normal, and when to stop and reassess.
Break-In Guide
How to Break In New Insoles
A graduated wear schedule that gives your feet time to adapt, day by day.
Comfort Guide
Arch Support in the Wrong Place
Arch length, not arch height, is usually the problem. How to tell the difference.
Durability
Insoles Flattening Too Early
What compression looks like, what accelerates it, and when it’s a fault versus normal wear.
A Simple Fix Path
Not sure where to start? Work through these three steps in order.
1
Identify the symptom
Use the table above to name what’s actually happening.
2
Check the simple causes first
Factory insole still in, wrong length, trapped moisture.
3
Adjust, then reassess
Give any change a few days before deciding it hasn’t worked.
Important: If you have diabetes, reduced sensation in your feet, an open wound, numbness, or pain that worsens, speak to a healthcare professional before changing your insoles. Educational guidance should not be treated as a diagnosis or medical treatment recommendation.
