When to Replace Insoles

Know when your Adidas insoles have reached end-of-life and need replacement for optimal comfort and support.

5 Clear Signs It's Time to Replace

The insole is noticeably thinner under your heel and ball of foot compared to edges.

Replace if: More than 50% thickness loss in high-pressure zones

Your feet feel the midsole directly, no spring or bounce remaining in the insole.

Replace if: Every step feels flat, especially on hard surfaces

Smell won't go away even after thorough cleaning and airing out.

Replace if: Bacteria has penetrated foam structure (cleaning doesn't work)

New arch pain, heel soreness, or general foot fatigue after normal wear duration.

Replace if: Pain is localized to shoes, not present in other pairs

Tears, holes, detachment from insole backing, or material breakdown.

Replace if: Any structural failure that affects foot positioning
