This is an adjustment to the built-in orthotic to accommodate a flat foot or flat arch. This is not an item that ships but rather an adjustment to the footwear. Choose this option if you have a flat foot or very low arch.
Do not add if you have a normal foot. This raised arch in the orthotic is designed to support your arch and equalize pressure - so our aim is match the shape of the orthotic to your foot shape. Call if you have questions.
