How should I clean and maintain these insoles?

To clean, remove the insoles from your shoes. Hand wash them separately using a small amount of mild soap or detergent and cool or lukewarm water. Gently rub the surface to remove dirt and sweat, then rinse thoroughly. Do not use bleach, strong chemicals, or put them in a washing machine, as this could damage the material, texture, or magnetic inserts.

After washing, press them gently between towels to remove excess water—do not wring or twist. Let them air dry completely, lying flat, away from direct sunlight, radiators, or other heat sources. It's crucial they are 100% dry before you place them back into your shoes to prevent odor or mold. For daily maintenance, simply airing them out after use can help keep them fresh. If you switch them between shoes, store the unused pair in a dry place.
