When
shoes do not
fit properly, they can cause parts of the feet to develop into
calluses,
bunions, uncomfortable corns, hammer toes and can also aggravate other
medical problems of the feet.
While
some foot problems
are genetic or related to stress injuries, many are caused by shoes
that
squeeze, scrunch, pinch, squish and rub. Women are about four times
more
likely than men to suffer foot problems as a result of poorly-fitting
shoes,
which can cause malformation of the feet.
Nearly 90
percent of women
wear shoes that are one size too small
Calluses
typically occur on the sole of the foot, on the heel or under the five
metatarsal heads (i.e., the area where the long inner bones of the toes
extend into the foot). These areas typically bear most of the pressure
and friction from standing and walking. As the callus thickens, it
causes
more pressure against the skin inside the shoe, causing pain.
Cornsare
thickened areas of skin that form in response to excessive pressure and
friction. They are the result of the body's attempt to protect the skin
and the structures beneath it. Corns are usually hard and circular,
with
a polished or translucent center, like a kernel of corn. They may
become
painfully inflamed in response to persistent, excessive pressure or
friction
and ulcerated when they rub against eachother. The most common type
develops
on the tops and tips of the toes and along the sides of the feet. These
are called heloma durums (hard corns) and are caused primarily by
improper-fitting
shoes and toe deformities.
Because hard
corns usually
are caused by a combination of narrow-toed shoes and toe deformities,
they
can be treated in two ways. One is to wear wider shoes or sandals when
possible.
A bunion
is a bump that develops on the inner side of the foot, near the base of
the first toe. It is caused by poor alignment of the
metatarsal-phalangeal
joint of the big toe (hallux). Physicians call this deformity "hallux
abducto
valgus" (HAV), a term that refers to the hallux abducting (going away)
from the midline of the body. It also refers to twisting of the toe so
the inside edge touches the ground and the outside edge turns upward.
Essentially,
it describes the deviation of the toe toward the outside of the foot.
The
condition worsens over time leading to discomfort and skin problems,
such
as corns and lesions, and difficulty walking.
Bunions
may be caused by
excessively tight, pointy-toed, or high-heeled shoes, and shoes that
are
too small. Women get bunions much more often than men do. Improper
shoes
exacerbate the underlying cause of flat, unstable feet.
Heel
pain is
one of the most common forms of foot pain in the United States. It can
largely be attributed to the stress on the feet caused by daily
activities
and exercise that magnifies misalignments in the feet, particularly if
improperly-fitted shoes are worn.
Physicians
use the terms
plantar
fasciitis and post-static
dyskinesia interchangeably to refer to heel
pain.
There are
many structures
attached to the heel bone (calcaneus). The two structures primarily
associated
with heel pain are the plantar fascia (band of connective tissue along
the bottom of the foot that supports the arch) and the flexor digitorum
brevis muscle. Typically, in walking, the arch starts to flatten as the
foot absorbs the weight of the body and these structures maintain the
arch
and stabilize the foot (see Anatomy of the Foot and Ankle). Normally,
they
accomplish this effortlessly. Excessive exercise and occupations that
require
people to spend a lot of time on their feet may stretch these
structures
beyond their limits. This stretching can lead to muscle tears and bone
spurs.
Bone
spurs on the heel occur
when muscle tension (usually on the flexor digitorum) pulls a piece of
bone away from the calcaneus. A bone spur usually appears on x-ray as a
fishhook-shaped structure. This sharp-edged deformity irritates the
nerves
in the heel and, combined with the strained muscles, causes heel
pain.
Poorly
fitted shoes exacerbate
the problem further. Many people who work all day in new or ill-
fitting
shoes experience heel pain the next day. Ill-fitting running shoes may
cause pain for weeks after a single run, as can playing 18 holes in
improper
golf shoes. This does not mean that a $100 pair of sneakers is
necessarily
better than a pair that costs $50; the fit is what is
important.
Sneakers
and athletic shoes
should fit properly, have plenty of cushioning to absorb shock, and
provide
support. There are different types of shoes for different sports. This
is more than a marketing gimmick. Certain sports, such as tennis,
require
shoes that provide lateral support and others, such as cross-training,
require shoes with a softer sole that conforms to irregular terrain.
A hammertoe
is a contracture—or bending—of the toe at the first
joint of the digit,
called the proximal interphalangeal joint. This bending causes the toe
to appear like an upside-down V when looked at from the side. Any toe
can
be involved, but the condition usually affects the second through fifth
toes, known as the lesser digits. Hammertoes are more common to females
than males.
The above
is just a sample
of conditions which may be caused by improperly fitted shoes.
Most
foot problems
can be prevented or alleviated by properly fitting shoes.
