Plantar fasciitis is the most common cause of heel pain, and you may have gotten for several reasons.  Plantar fasciitis is the inflammation of the band of tissue that starts at your heel, goes across the arch, and inserts at the ball of the foot.  The inflammation of this band of tissue is what causes pain.  It affects all foot types - those that have high arches, and those with relatively flat arches.  It could be due to an increase in activity, a change in activity, or a activity on a new surface such as hard wood or concrete floors that  you are not used to.  One cause may be that the current shoes you are in are no longer supporting the arch, such as attempting to run in a worn out pair of gym shoes.  Shoes without an arch, such as flip flops or ballet flats, may also cause the plantar fascia to stretch out repeatedly as you walk causing irritation and inflammation.  Regardless of how you got the heel pain in the first place, the most important thing is to have your foot examined by a foot and ankle specialist at PPFAC and get a proper diagnosis and come up with a treatment plan.  The sooner it is diagnosed, the sooner it can be treated and you can learn ways to prevent it from returning.
