Foot type is determined by the shape and structure of the foot. It affects the reduction of impact on the foot while walking, jogging or running. The quickest way to determine your foot type is to take the “Wet Foot Test”.
The Wet Foot Test is done by wetting your feet and then standing on a surface that will leave a visible foot print, such as paper. Observe the shape of your foot print and match it with one of the shapes at the bottom.
If you see about half your arch, then you have the most common foot type.
The motion for this type of foot type is to land on the outside of the heel and roll inwards, absorbing the shock. This foot type is the most ideal and can wear just about any shoe.
If you can see almost your entire footprint, then you have a low arch (or flat feet). This means you are probably an over-pronator, as your foot rolls inwards too much. This can increase your risk of injuries (such as plantar fasciitis) as shock is not absorbed efficiently. Over-pronators should be going for stability shoes or motion control shoes.
If your footprint shows a very thin or even non-existent line connecting the heel with the ball of your feet, then you have high arched feet. This is the least common foot type and indicates that you are a under-pronator (or supinator). This can increase your risk of injuries (such as iliotibial band syndrome) as it allows too much shock to travel up your legs. Under-pronators should be going for cushioned neutral shoes with plenty of flexibility to encourage foot motion.
