Under normal circumstances, your plantar
fascia acts like a shock-absorbing bowstring,
supporting the arch in your foot. But, if
tension on that bowstring becomes too great, it
can create small tears in the fascia.
Repetitive stretching and tearing can cause the
fascia to become irritated or inflamed. The
causes of plantar fasciitis can be:
Plantar fasciitis is common in long-distance
runners. Jogging, walking or stair climbing
also can place too much stress on your heel
bone and the soft tissue attached to it,
especially as part of an aggressive new
training regimen. Even household exertion, such
as moving furniture or large appliances, can
trigger the pain.
Some types of arthritis can cause inflammation
in the tendons in the bottom of your foot,
which may lead to plantar fasciitis.
Although doctors don't know why, plantar
fasciitis occurs more often in people with
Being flat-footed, having a high arch or even
having an abnormal pattern of walking can
adversely affect the way weight is distributed
when you're on your feet, putting added stress

Shoes that are thin-soled, loose, or lack arch

with high heels, your Achilles tendon - which
is attached to your heel - can contract and
shorten, causing strain on the tissue around
