There are three basic types of feet based on the heights of your arch – low arch (i.e. flat feet), normal arch, and high arch. To determine your foot type, you could simply ask your friend or spouse to observe your foot arch as you’re standing straight on the ground and see which of these illustrations give the best match. You could also do a watermark test, i.e. wetting your feet thoroughly (but not too wet or else you could get an inaccurate reading) and stepping on a piece of brown paper to see what shape it forms. Below are the possible footprints that determine the types of your feet:

Alternatively, you can consult an orthopedist or getting a foot scan from an orthotics/orthopedics outlet near you for more accurate reading.
