Yes, you can wear. If you have flat foot it will take more time to adjust as they don’t have any artificial support. You need to plan a feet strengthening journey with proper exercise and footwear. It will take time but yes you can absolutely wear them. There is a commonly held belief in foot care that flat feet must be supported. But it’s unclear what exactly the definition of a flat foot is, and what complications it leads to. Arch support in traditional footwear does not teach you how to use your feet well and it doesn’t allow you to use your foot muscles, so it might actually hinder rather than help. Foot function is a much bigger indicator of success than the height of your arch. As long as there is no pain, dysfunction, or underlying pathologies, then both kids and adults can wear barefoot shoes even with flat feet.
