Why Do Diabetics Need Special Shoes?

There’s a question that we get in our Blacksburg and Roanoke offices quite frequently – and that is, “Why is it that your diabetic patients require special shoes?”

To understand the answer to this question, one must first understand the diabetic foot. One big reason why it is important for any diabetic person to carefully monitor and control blood glucose levels is that when uncontrolled, many complications can arise. Some complications that are frequently seen in our office are nerve damage, decreased blood flow, and foot and joint problems. All of these problems can and do affect the feet.

Besides the bladder, bowel and stomach issues that can arise from diabetic neuropathy, poor sensation can have devastating effects on a patient’s feet without proper care and attention. Inability to feel pain, pressure or temperature can easily allow for rubs, blisters, burns and other injuries to go unnoticed.

Feet are sensitive and the blood supplying oxygen to the lower extremities may be reduced without you even being aware of it. The decreased oxygen delivery to the feet from poor circulation results in slower healing and nail growth.

Uncontrolled blood glucose levels can be inherently dangerous. “Rollercoaster” blood sugar levels can damage tissues and cells. An elevated blood glucose level can cause dehydration and dryness of the skin as well as promote the growth of bacteria and fungi (since sugars are a good food source for these organisms). Because of this, bladder, gum, and skin infections are common in our diabetic patients with high sugar levels. 

So, Why Special Shoes?

-          Proper shoes are the first line of defense against injury and infection.

-          Well fitting shoes are comfortable and allow proper circulation in the feet.

-          Proper shoes will allow your feet to breathe while still protecting them.

-          Proper shoes can prevent the development of ulcers, blisters and fungus.

How are these shoes different?

-         Deeper and wider to accommodate diabetic inserts, allow more room for feet, and reduce possible pressure points.

-         These shoes provide excellent support which is recommended for anyone buying shoes.

-         Most have a breathable fabric upper to promote good air circulation within the shoe.

-         Most are custom ordered for size or even custom molded to a patient’s foot.

-         The toe boxes are roomier to prevent pinching or squeezing the toes as well as to allow for more room for foot deformities.

-         Many are easily adjustable or have elastic which makes it easier to put on without making the shoe too tight or too loose.

-         Available with Velcro to make putting on shoes easier for patients with peripheral neuropathy who can not feel their fingers well enough to lace shoes.

Foot Care Myths

Old wives' tales and myths like that example are fun to laugh at. We believed them growing up. "Step on a crack and you'll break your mother's back." But there are other myths that are no laughing matter, especially when they involve your health. Here are four myths about foot care and the realities behind them.

Myth: My foot or ankle can't be broken if I can walk on it.
Reality: It's entirely possible to walk on a foot or ankle with a broken bone. But it's not a smart idea. Walking with a broken bone can cause further damage.  It is crucial to stay off an injured foot until diagnosis by a podiatrist. Until then, apply ice and elevate the foot to reduce pain.

Myth: Shoes cause bunions.
Reality: Bunions are most often caused by an inherited faulty mechanical structure of the foot. It is not the bunion itself that is inherited, but certain foot types make a person prone to developing a bunion. While wearing shoes that crowd the toes together can, over time, make bunions more painful, shoes themselves do not cause bunions. Although some treatments can ease the pain of bunions, only surgery can correct the deformity.

Myth: A doctor can't fix a broken toe.
Reality: Nineteen of the 26 bones in the foot are toe bones. There are things that can be done to make a broken toe heal better and prevent problems later on, like arthritis or toe deformities. Broken toes that aren't treated correctly can also make walking and wearing shoes difficult. A foot and ankle surgeon will x-ray the toe to learn more about the fracture. If the broken toe is out of alignment, the surgeon may have to insert a pin, screw or plate to reposition the bone.

Myth: Corns have roots.
Reality: A corn is a small build-up of skin caused by pressure or friction. Many corns result from a hammertoe deformity, where the toe knuckle rubs against the shoe. The only way to eliminate these corns is to surgically correct the hammertoe condition or wear extra depth orthopedic shoes that eliminate the pressure. Unlike a callus, a corn has a central core of hard material. But corns do not have roots. Attempting to cut off a corn or applying medicated corn pads can lead to serious infection or even amputation. A podiatrist can safely evaluate and treat corns and the conditions contributing to them.
