hello aradhya!!

There’s a simple way to spot flat arches – simply stand in front of the mirror and check the gap in the middle of your feet. If the gap doesn’t exist, it means you have flat feet.

And If you want to check indiviually for each foot please try any of the following steps and check :

Step 1

Walk in Wet Sand

Walk barefooted through wet sand at the beach. Examine your footprints closely. If you see that each footprint is "full," meaning your entire foot has left an impression on the sand, you are flat-footed. If you notice your footprints show a "cut out" where your arch did not press into the wet sand, you are not really flat-footed.

Step 2

Sit on a chair and cross your bare right foot over your left thigh. Flex your right foot and look at your instep. If you can see a deep, unmistakable curve along your arch bed, you are not flat-footed. If you notice that your arched foot remains flat along the medial arch, you are probably flat-footed.

Step 3

Step with bare feet onto a memory foam cushion that you can buy as a scrap from mattress stores. Step off the cushion immediately and see if your footprint is full — displaying no real arch, meaning you are flat-footed, or if you see a "reverse C" shape — meaning you do have an arch.

Being flat-footed does not mean you have a disability. If your ankles turn out or in when you walk or run, wear shoe inserts that support your arch bed so that you cannot pronate or supinate. If you experience pain in your arches, consult a podiatrist who can assess you and assign appropriate physical therapy-type exercises for you to help rebuild your arches.

hope this helps

thank youu
