At first, you may feel a bit strange due to the arch support insole, but this is a normal reaction. We recommend wearing it in your regular shoes for at least 2 weeks to fully experience the comfort and support.
 If your body is unbalanced, the arches of your two feet may differ in height, which can create an uneven feeling—this is completely normal.
No. Please remove your old insoles and use only the WALK48 insole by itself.
