A flatfoot deformity is where the arch on the inside border of the foot is more flat than normal. Flatfoot deformities can occur in all age groups, but appear most commonly in children. Some of these children grow up into adults who have feet with normal arches, but many of these children have pain related to their flatfoot deformity throughout their lives. It is very important that children with flatfoot deformity be evaluated by a podiatrist to determine if they need treatment to prevent future pain or deformity in their feet.

When the young child starts to first walk at about the age of 9-15 months of age, the foot has a fat or chubby appearance where there is a less bony architecture apparent in the foot. At this point in the development of the foot, it is very difficult to evaluate whether the child will have future problems with a flatfoot deformity.

At the ages of two and three, the child's foot starts to show more of its characteristic shape since the foot is less fat and the bones are more prominent. If the child has a flatfoot deformity at the ages of two to three, then it is wise to have the foot examined by a foot specialist such as a podiatrist. The reason that it is important to have the feet examined at this age is because the young foot is still largely made of cartilage, with less bone than would be present in the adult foot. Since cartilage is relatively soft, the abnormal forces caused by a flatfoot deformity may cause permanent structural alterations to the bones and joints of the foot that will persist into adulthood.

The flatfoot deformity in children causes a number of changes to the structure of the foot which is easily recognizable by the trained podiatrist. Flatfoot deformity causes the inside arch to be flattened, causes the heel bone to be turned outward, and causes the inside aspect of the foot to appear more bowed outward than normal. Most cases of flatfoot deformity in children are also associated with excessive flexibility in the joints of the foot which is commonly caused by ligamentous laxity.

Since the flatfoot deformity causes some instability of the foot during gait, children with flatfoot deformity may have complaints in the foot such as arch, heel or ankle pain which is generally associated with increased standing, walking or running activities. However, since the excessive rolling inward of the arches of the foot also make the leg and knee more turned inwards, children with flatfeet may also complain of pain in the low back, hip, knee, or leg due to the abnormal mechanics of the foot which is created by the flatfoot deformity.


As mentioned above, the pediatric flatfoot deformity can be diagnosed at a very early age, but is unlikely to be properly diagnosed unless the doctor is a foot specialist, like a podiatrist, and is familiar with the intricacies of the structure and biomechanics of the foot. After speaking with the parent and child, the podiatrist will examine the foot both while the child is not bearing weight but also while the child is standing, walking or running. Often, the family history is also taken since the foot should be examined closely if the child has a close relative who had a painful flatfoot deformity as a child or adult.

During the examination of the child, the podiatrist is looking for abnormal structure or function of the foot and lower extremity, which could lead to either problems during childhood or adulthood. X-rays may be taken of the foot if a significant pathology is noted or suspected. The more severe the flatfoot deformity and the more significant the complaints in the foot or lower extremity, then the more likely the podiatrist will recommend specific treatment for the flatfoot deformity.


If the child has a mild flatfoot deformity and no symptoms, then generally no treatment is recommended other than possibly yearly check-ups by the podiatrist. If, however, the child has a moderate to severe flatfoot deformity and does have significant symptoms in the foot or lower extremity, then treatment is indicated.

Treatment generally starts with both supportive shoes, such as high tops, and some form of in-shoe insert such as arch padding for the milder cases of flatfoot deformity. More significant cases of flatfoot deformity may require more exacting control of the abnormal motion of the foot such as that offered by functional foot orthotics. Functional foot orthotics limit the abnormal flat arch shape and rolling in of the heel bone during standing, walking and running activities which helps not only improve the appearance and function of the foot, but also greatly reduces the symptoms in the foot or lower extremities. Calf muscle stretching exercises are also commonly prescribed for children with tight calf muscles since the tight calf muscles can worsen the flatfoot deformity with time and make the child's symptoms worse.

If the child has a severe flatfoot deformity and disabling symptoms which does not respond to foot orthotics, shoes and/or stretching, then foot surgery to correct the flatfoot deformity may be indicated. Flatfoot surgery is done only rarely for those children with the most severe deformities. Of course, the benefits of the surgery should be considered along with the risks associated with the surgery and a second surgical opinion is always recommended when considering flatfoot surgery on your child.

Sock technology has really advanced and can be an important part of protecting your feet.  The challenge is when your feet sweat, where does the moisture go?  For some of us it is the triple digit temperatures and for others it may be the required work boots they wear for work or the long work out down on the trail...either way your feet are sweating in your socks.  

We recommend moisture wicking socks (also called Coolmax, Drymax) which wick the moisture away from your feet and keep them dry.

Keeping your feet dry is an important part of preventing tinea pedis (atletes feet) and onycomycosis funal toenails).

Protect Your Feet From Skin Cancer

Skin cancer on your feet? Yes, it definitely does occur. In fact, melanoma of the
foot is particularly fatal because people rarely think to look for the disease. (Did you know that Bob Marley died of malignant melanoma of the toe?)
Early detection is important, so be sure to check your feet regularly. If you find
suspicious spots on the soles of your feet, between your toes, or under your
toenails, call our office right away for an appointment.
Think “ABCD” to detect melanoma:
Asymmetry - The shape of the one half does not match the other.
Border - The edges are often ragged, notched, blurred or irregular.
Color - The color is uneven or varies from one area to the other.
Diameter - Melanomas grow in diameter, whereas moles remain small.
A spot larger than the size of a pencil eraser (about 5 millimeters) may
be cause for concern.

What’s the best way to prevent skin cancer? Wear SUN SCREEN!

Go local.... with your sun screen.  Texas based comapny Supergoop.

Lawnmowers and Feet Don’t Mix

Keep your feet and those around you safe this summer by using caution when mowing your grass.
Did you know the blades on lawnmowers can spin at 3,000 revolutions per minute and produce
three times the kinetic energy of a .357 handgun? Yet, each year our office continues to see patients
who have been hurt while operating a lawnmower barefoot.

Enjoy the beautiful summer season but be sure to protect
your feet and ankles from yard-work injuries and mishaps.
Take caution when mowing and remember:

-Don’t mow wet grass. Losing control from slipping on rain-soaked grass is the leading cause of
foot injuries caused by power mowers.
-Wear heavy shoes or work boots when mowing—no sneakers or sandals.
-Don’t allow small children to ride on your lap while on a lawn tractor. Children can be severely
injured by the blades when getting on or off the machine. Keep children away while mowing.
-Mow across slopes, never go up or down.
-Never pull a running mower backwards.
-Use a mower with a release mechanism on the handle that automatically shuts it off when your
hands let go.                                                                                                                                                                             

If you or someone around you is injured by a mower, be sure to seek treatment immediately.
Superficial wounds can be treated on an outpatient basis at our office or at your closest emergency
department. More severe wounds may need surgical intervention to repair damage.
Caring for your lawn can be an enjoyable summer experience, just make sure you use caution to
protect yourself from injury.

The average moderately active person takes about 7500 steps a day. Assuming every day the person walks, an eighty year old person who began walking at one year of age, would have taken 216,262,500 steps in their lifetime. An average person, with an average stride, living to this age of 80 will walk about 108,131 miles. Given this is the average (and Austinites are above average!), it is important to keep your feet in good health.

Good foot health can improve the health and well-being of our whole body. To start, begin by choosing smart foot wear with the right insole for your foot’s needs. Just remember, feet aren’t supposed to continuously be in pain; if you're feet are hurting, get them checked out by a podiatrist.

All this being said, let’s celebrate Foot Health Awareness Month. Whether that be by increasing our weekly physical activity, enrolling in a race or a sports program or by simply... taking a walk!
