Before usage, make sure the product fits well in the shoe. The heel of the insole should be placed against the back of the shoe.
For some people, orthotic insoles may take time to feel comfortable. Feet need to get used to the structural properties of the insole, so a break in period may be necessary. If needed, build use gradually by wearing the In-Balance Orthotic Insoles for an increasing number of hours each day until you can wear them all day.
