Do I have to remove existing shoe inserts?

You can replace the existing shoe insoles with EASYFEET® with the hard TPU side facingdown.

What type of shoes does it fit?

EASYFEET® insoles fit most of the footwear, except dress and heel shoes.

How often should I replace the insoles?

It is recommended with other insoles that you replace them every six months or so. I am not sure when you should replace these. I would replace it if it seems like they are breaking down or are not offering the support that they once had.

When I can feel the effect?

You can feel the effect after the first week, in case you wear the insoles regularly. However, we strongly recommend starting with 2-3 hours per day, so your feet can get used to arch support. Then increase the time every day.

How can I return the insoles?

All our clients can return or exchange the insoles if they are not satisfied with the product. You can return your insoles even if they have been trimmed.
