How to Determine Foot Arch Type

By: Mayo Clinic Health System

Are you thinking of buying a new pair of running shoes? Distance running places tremendous pressure on the feet, ankles and legs, whether you’re a casual 5K finisher or a competitive marathoner.  Running  can generate impact force through your legs that is three to five times your body weight.

Choosing the right shoes can improve running comfort and performance. They also can prevent injuries.

One thing to know before you buy is what type of foot arch you have. If you’re not sure about your foot arch type, dip your foot in water, step on a piece of cardboard and examine the print that remains. After examining the print, use the Determine Your Foot Arch chart.

Here are descriptions of arch types and shoe characteristics that complement and support your foot:

Normal Arch (Medium)

If the middle part of your arch is about half filled, this means you have a normal arch. Your arch naturally supports your body weight and pronates, or rolls in, under a normal load.

Look for shoes with firm midsoles and straight to semi-curved lasts – the shape of the sole and the footprint the shoe is built around – and moderate rear-foot stability.

Flat Arch (Low)

If your footprint looks like a complete foot, then you have a flat arch. Your arch probably collapses when you walk or run. Your low arches may contribute to muscle stress and joint problems.

You could benefit from a running shoe with a straight last and motion control to help stabilize your feet.

High Arch (Low)

If you see little of your footprint, you likely have a high arch. High arches may cause excessive strain on joints and muscles. Your feet may not absorb shock well, especially if you perform a lot of impact or jumping activities.

Look for shoes with cushioning to compensate for your lack of natural shock absorption and a curved last.

Comfort Counts Most

Use these tips as a guide for choosing the right running shoe for your feet. But when the sole meets the road, comfort and how the shoes fit are what count the most toward performance and performing injury.
