Treating Calluses

Treating Calluses

Calluses on your feet are simply hard thickened skin, mostly there for protection of areas of the foot that may be under pressure or friction. This can be from normal walking, running, most other sports, shoes, socks, and walking barefoot. Most of this hard thick skin is purely protective and is of no clinical significance. And it is usually not painful. Most of us get a bit of this protective callus and need not worry about it. This normal callus is called physiological callus. There is another form of callus that gets too thick and starts to be painful. This is called pathological callus. This callus is caused by excess pressure on and area of the foot and that normal callus then progresses and gets extremely thick and painful. Abnormal foot biomechanics, foot deformities and some dermatological conditions cause this callus. This is an abnormal type of callus and needs treatment. Treatment You can take care of a normal callus yourself. You can apply a foot cream to the area and that will keep the callus soft. Nutraplus is good.  Do this daily, especially if you walk barefoot, or wear sandals a lot. When you run apply Vaseline to these areas for lubrication. If you have an abnormal callus then you need to reduce the pressure that is causing it. Check your running shoes out replace them if they are old and collapsed. File the hard skin down with a file or a pumice stone a few times a week. No knives or scalpels please.  Also use a foot cream daily. Nutraplus is good. Vaseline those feet for running. If you cannot manage these lesions yourself seek professional help. This information and / advice is the opinion of the author in his capacity as a qualified and registered podiatrist.

Which Foot Type and Shoe?

There are basically three foot types. 1 the normal / neutral foot, 2 the high arched foot and 3 the flat / pronated foot. 1 This so called normal / neutral foot is the ideal normally functioning foot. It is an efficient foot and it is not very prone to biomechanical or running injuries. 2 The high arched foot is  not a very common foot. Less than 5% of the population has this type of foot. This foot essentially is a stiff non shock absorbing foot. By not absorbing the shock the foot, leg, knee, hip and back gets the shock wave from running. This is not the best foot to have. 3 The flat / pronated foot is common. This type of foot collapses inwards when walking and running and in this position it is not a very efficient foot. It also can be a cause of many foot and leg injuries in running. SHOE CHOICE FOR THE FOOT TYPES. The choice of the correct running shoe is very important to improve your performance and to reduce the risk of injury. My best tip is if you are running in a model of shoe and they work for you then don’t change it. If you are forced to change them because they are discontinued, find another model as close to them as possible in terms of support and cushioning. The rules of shoe choice are simple. If you have neutral (normal) functioning feet you need to wear neutral running shoes. Every shoe company has neutral shoes in their range. If your feet are mildly overpronating / flat you need to wear mild antipronation or stability running shoes. If your feet pronate excessively / very flat you need strong antipronation or motion control running shoes. If your feet are high arched / supinate (turn out) too much then wear neutral to soft running shoes. What is the difference between a male and female foot? Anatomically there is no difference between a man and a womans foot. They both have the same anatomical bones and structures. The difference is in the shape of the foot and the function of the foot. A womans foot is generally narrower at the heel and wider in the forefoot. A womans foot generally pronates / rolls inwards more than a mans because of wider hips. A womans foot may have more flexibility. Most shoe companies...

Pronation and the Norm…

The foot is designed to pronate / roll inwards a little when we walk or run. This slight pronation is NORMAL PRONATION. The pronation is a shock absorption mechanism of the foot. SO IT IS NORMAL. When the foot pronates too much – excessive pronation – it can cause or contribute to injury in the foot or higher up. So if you pronate NORMALLY then you do not do anything about it. If you pronate excessively AND IT IS CAUSING OR CONTRIBUTING TO INJURY then get an antipronation / supportive shoe. If necessary get an orthotic device to support you. I am going to try and simplify this matter of pronation / overpronation and underpronation / supination. The foot has a complex anatomical structure but in motion it has an even more complex biomechanical function. When running the heel contacts the ground in a turned in position called inverted. From there the foot rolls inwards (pronates) and the forefoot contacts the ground. This normal pronation can be measured to be between 2 and 4 degrees. This phase of the foot function is to absorb shock. From this pronated position the foot rolls to the outside and this is called supination. As this happens the foot locks into a rigid lever to propel us forward.  The foot should move into these various positions at the right time for it to function efficiently and normally. This type of foot is called a neutral or normal functioning foot. In the running population out there most runners do not have these neutral / normal feet. The most common biomechanical malfunction is that of excessive pronation. This means that when the foot is meant to pronate it does not stop at the normal amount and keeps on rolling into an abnormal position called excessive pronation. This abnormal biomechanical malfunction may cause a variety of injuries. There are many runners out there that excessively pronate and do not have any injuries. The opposite of this excessive pronation is excessive supination. This means that the foot does not pronate when it should and the foot stays turned out excessively to the outside. This is also abnormal and may be a cause of injury. To see if you pronate excessively or supinate excessively you need a full biomechanical by a professional. This will include a running shoe examination, a static clinical examination and a running examination. My...
