Things You’ll Need:
Lay a piece of cardboard flat on the ground.
Fill a basin with water and set it next to the cardboard.
Dip one bare foot into the basin and allow the foot to drip dry for a few seconds.
Step onto the cardboard and then lift your foot up.
Examine the foot print left behind by the moisture. If moisture creates a footprint where the areas of the ball of the foot and heel are connected by a thick band of moisture that is larger than an inch an a half or so you have flat feet. If the ball of the foot and heel are connected by a thinner band of moisture that is between a half an inch and one and a half inches your feet have normal arches. If the band of water joining the ball of foot and heel splotches is around half an inch or thinner (or not present at all) you have high arches.
People with high arches tend to need shoes with a less supportive structure while those with flat feet benefit more form stable structured shoes.
The type of shoe you wear can have a dramataic impact on the comfort of your feet. Wearing the wrong shoes for your feet can lead to injury and reduced training time. It is important to your foot type in order to purchase the correct shoes, and to monitor your feet for discomfort and pain; if your feet are not comfortable it is best to stop running and find new footwear to avoid complications.
