To ensure that you can enjoy your orthopaedic insoles for a long time, you should remove them from your shoes after wearing them and give them fresh air at room temperature. Make sure that you do this:
Do not place them on a radiator or other direct heat source.
Never blow-dry your insoles.
Temperatures of 40°C / 104°F and above can change the fit and can also destroy the materials with which our orthopedic insoles are designed.
