If your dress shoes didn’t come with adequate arch support, you can ensure that your arches are properly supported by adding your own custom insole to the shoe.
When your arches aren’t adequately supported, your bodyweight gets distributed unevenly across your foot, which may place extra strain on certain parts of the foot and cause pain or discomfort.
Insoles help to remove that pressure and increase the comfort of dress shoes. You should use a ¾ insert for dress shoes in order for them to fit comfortably.
