Know your foot! published a simple method to discover if you have a foot with a flat or high arches, useful to choose the right pair of running shoes.

The beautiful illustrations are realized by Dan Fuehrer:

Pour a thin layer of water into a shallow pan.

Wet the sole of your foot.

Step onto a shopping bag or a blank piece of heavy paper and stand on that leg.

Step off, look at the shape of your footprint and compare it with this images:

NORMAL (MEDIUM) ARCH — Most runners with this pattern can wear just about any shoe.

FLAT (LOW) ARCH — Usually, we would recommend shoes with more stability

HIGH ARCH — We would usually recommend you use a well-cushioned shoe with little or no arch support or stability features.
