Orthotics will help you ease foot pain. You can insert them into your walking shoes, to enhance whatever support the shoe already gives.
A common concern is what type of impact the inserts will have on the shoes. Make sure to get inserts that fit in your shoes. Simply make sure that it corresponds with your shoe size.
An insert will help you get more comfort from your shoe and can also help you fill it more if your shoe seems to have a little too much room.
