Sweaty Feet

Sweaty feet affect everybody at some time of their lives. The complaint can be seasonal -worse in the warmer months – but can be present at any time of year. The medical term is hyperhidrosis (excessive sweat production) and if there is an accompanying bad odour, it is called bromidrosis.

There are many causes. The most common is poor foot hygiene associated with footwear with a high synthetic material content. Socks, stockings or tights made of nylon also cause the feet to sweat excessively. In teenage years glandular changes are a frequent cause amongst males and is made worse by poor hygiene and footwear. Occasionally, there is a systemic problem which shows in increased sweating of the hands and other body parts. Whenever we exercise, we develop sweaty feet, which is is quite normal, but it does lead to the smelly foot and shoe syndrome.

An excessively sweaty foot is susceptable to the development of fungal infections and because it is important to differentiate between sweating and fungal infections, I’ll write in detail about fungal infections in the future.

Treating sweaty feet needs patience and perserverence. Daily washing with soap and water is essential. Then dry feet thoroughly. Try to avoid wearing shoes with synthetic uppers and soles. Make sure your socks contain high percentages of cotton or wool. Read the labels to see what the socks are made of. Try using an anti-perspirant under the arches of your feet. There are some products advertised specifically for this application. Podiatrists usually recommend ‘Spiritus Pedibus’ also called Foot Spirit. It contains 3% Salicylic Acid in Ethyl Alcohol. Occasionally a weak solution of Formalin can be prescribed. Obviously any opportunity to have your feet bare in fresh air will help. So wear sandals whenever possible. However, beware of plastic and synthetics, go for leather if you can. If the condition is really severe, a change of socks may be necessary during the day.

There is a surgical procedure called a sympathetomy – which must be performed by a specialist surgeon – for very severe sweating of the hands and feet.

Smelly feet are usually caused by the bacteria which live on our feet normally, not being washed off thoroughly. They can of course be caused by the materials themselves, especially some rubbers. Washing and drying is a good start followed by any of the above treatments. Naturally if you favourite trainers make your feet smell, but your normal shoes don’t, you have a hard choice to make!

Powder is often used for sweaty feet, but be careful since it tends to solidify between the toes.

Sweaty feet are a common complaint and they can be embarassing. However, treatment is often very simple, starting with an intensive foot hygiene routine.

Podiatry and the Child with Arthritis

In podiatry, for the child with arthritis, we find that foot problems are not necessarily caused by the arthritis alone. Before the disease is correctly diagnosed, swelling, pain and lack of mobility are the main signs and symptoms. This usually affects the hands, knees, feet and ankles. Malfunctions of the foot, ankle and leg as a result of painful joints usually respond to medication. However, many structural problems [what podiatrists call biomechanical anomalies] remain, because they were present before the arthritis developed.

I have found that podiatric intervention is necessary and effective during the painful stages at the start of medication and after the disease has gone into remission following medication. The intention is to balance or control foot function, thereby reducing the load on the painful foot joints. This counteracts the effects of these underlying anomalies and aims to protect the feet from long-term damage.

Even children without foot pain but with significant biomechanical anomalies are prescribed foot orthotics. This is at present only an opinion, but we are recording all interventions at our clinic in an attempt to collect some meaningful data.

However, often the initial treatment involves making sure that the footwear is a correct fit. Many children that I see choose to wear soft slippers because their feet are painful and school shoes hurt. Slippers make matters worse as they give neither support or protection to the feet. Fortunately we can request that these children be allowed to wear trainers and so far teachers have been co-operative. For the really poor patients we actually buy an appropriate trainer.

The use of foot orthotics always stimulates debate. There is published research to show the benefits of prescription foot orthotics for adults with rheumatoid arthritis, but to date evidence for children is scarce. By using foot orthotics for all children with biomechanical anomalies with or without pain, we hope to prevent them from developing serious foot function problems as adults.

In some cases, we start by using a very basic treatment of figure 8 crepe bandage to support painful ankle joints. This can be easily taught to family members and starts to get the family involved in treatment – especially when they experience a reduction in pain and improved foot function.

I read in the June 2008 edition of PodiatryNow (the monthly Journal of the Society of Chiropodists and Podiatrists, in the UK), that “a 3-year trial is to commence aimed at reducing pain, stiffness and deformity in the feet of up to 60 children and young people.” The study is a cooperation between academic podiatrists from Glasgow Caledonian University, the Royal Hospital for Sick Children in Yorkhill and the Centre for Rheumatic Diseases at the University of Glasgow.

They have been awarded nearly 90,000 British Pounds, about 1.3 million SA Rands. Is there anybody reading this who would like to fund similar research at our clinic at Chris Hani Baragwanath Hospital in Soweto? (Subject to all the necessary protocols)!!

This type of research will enable us to be much more accurate in our interventions for foot problems in the child with arthritis.

Arthritis Affects Children’s Feet

J.I.A. or juvenile idiopathic arthritis is just one of the manifestations of arthritis in children. Just like adults children get pain, stiffness in the morning that can last for some hours, restricted movement of their joints, swelling of their hands and feet. In other words serious incapacity. Unlike the adult form where we see a pattern of rheumatoid arthritis starting to affect women mainly around the age of 40, in children it can happen anytime.

Awareness is the key for both parents and health care professionals. I have been seeing children with local areas of tenderness or pain under the heels, or at the back of them. Pain along the soles of the feet. Ankles that are painful all the time either when moving or resting. Showing reluctance to run around because of the pain. Complaining of swollen and painful toes. Not wanting to wear their school shoes because they hurt. There are many other signs and symptoms that usually the doctor will identify.

Some of my patients are so badly affected by arthritis that they are only able to wear soft slippers to school. Fortunately a donor has offered to provide appropriate soft but firm footwear for them. Some children are completely pain free thanks to the medication that has been prescribed, but they have structural foot problems and so need some form of support – usually with an orthotic – but often just a decent shoe and some advice is enough.

The secret of success in managing these children is teamwork, and I am lucky to be part of the paediatric rheumatology team at Chris Hani Baragwanath Hospital. The specialist doctors are able to prescribe the appropriate medication which frequently brings relief to the painful joints and removes symptoms.

Don’t ignore the child with a painful foot. It probably isn’t arthritis, but it might be.

More Foot Pain For South African School Children?

Thousands of South African children go back to school tomorrow. How many with foot pain?

We don’t know the facts, because the research hasn’t been done. But as children grow, so do their feet. So it’s a safe bet that many feet will be pushed into shoes that were bought at the beginning of the school year in January and are too small 6 months later in July.

On the other hand there will be some children who will suffer the discomfort of a brand new pair of school shoes! It’s not true that shoes have to be “worn in.” They should fit properly and be comfortabl from the start.

Most children wont tell their parents that their shoes are too small, because the soft, developing bones can be easily squeezed and squashed into position. In addition, in the current economic climate, the cost of a new pair of school shoes often has to be balanced against food, rent or travel expenses.

Try to look at your children’s shoes as soon as possible after the start of the term. They have probably complained about having to wear them anyway – having not worn them for a month. Get them to stand up in their school socks and you press gently on the end of each shoe to find the ends of the toes. If there isn’t a finger space at the end, they are too short.

Don’t try the other method of pushing a finger down the back of the foot behind the heel. The shoes should fit around the heels and allow the feet to lie nicely in their normal position. Check also for uneven wear on either side of the shoes – this shows flattening or ‘out-turning’. If the shoes are deforming you should get to see a podiatrist for a check up.

A final word on hockey, rugby and soccer boots. If your child complains that the soles of the feet are sore, have a look for red marks over the areas where the studs are. You probably need to put a soft cushion insole inside to limit stud pressure.

Can’t wait for the next school holidays!

Outrageous footwear!

High heels – of course they damage your feet. But women still buy them. Just take a look at an outrageous South African blog: Google- Shoegirl South Africa and see what you get!

Apparently a new fashion trend is to wear socks with your high heels. Socks with high heels? Almost as bad as socks with sandals for men.

Even better is the website for FitFlops, yes you read correctly. I saw them with my wife at a Johannesburg shoe store last Saturday. What about footwear advertised as: The flip flop with the gym built in! Cushioned heel absorbs 36% more shock than regular footwear. Micro wobble-board midsection slows eversion rate by requiring 15% more energy to walk. Firm toe area promotes faster toe-off.

And the result? Firmer buttocks and leg muscles. One wearer says she does feel like she has just done a workout after wearing them.

They are available through one string of outlets – I’m not advertising them! Check the website. www.fitflop.com

I’m dying to know more about them.

Here’s another idea, from Bignews page 14 January 2008.(This is a local business newspaper.)Transparent shoeboxes.(Very politically correct in SA today!). Boitunelo Mofokeng has obtained the rights to exclusively distribute Shoebby, a transparent shoe box manufactured in the United States.

So no more searching for ‘that’ pair of shoes, because all your pairs are visible in these neat transparent boxes. For the guys it could mean the end of sifting through that disorderly pile of assorted shoes in the bottom of the wardrobe! Contact Mofokeng at 082 453 8692.

Goodnight!

Can High Heels Heal?

‘Walking on sunshine.’ ‘Sexual heeling.’ ‘Toeing the line.’ All headlines for articles recently printed in the South African press taken from The Telegraph, The Sunday Times and The Times respectively, all from London. Toeing the line is all about the Chinese tradition of foot binding and I’ll pick up on that later this week.

The other articles are all about the benefits and effects of wearing high heels! Both suggest that wearing high heels is sexy and in ‘sexual heeling’ the research of a University of Verona urologist, Dr Maria Cerruto, is reported where she tackled “bizarre” theories about the effects of wearing high heeled shoes. The idea of sexual heeling refers to the Dr Cerruto’s assertion that pelvic floor activity is affected.

Traditionally we have blamed high heels for a variety of ailments, such as bunions, stress fractures, knee pain, lower back pain and increased risk of arthritis. South African research by Drs. Zipfel and Berger of The University of the Witwatersrand in Johannesburg showed scientific proof that wearing shoes had bad effects on the wearers when compared to unshod people. (I know this was on old bones but they have the proof). Dr. Cerruto’s evidence is due to be published in the journal European Urology. Since I am concerned with your foot health, I’ll leave that train of thought for you to follow.

However, in the article there is a comment from a UK fitness instructor who runs classes in London for women with high heels called Sweat and Stilletos. These sessions are designed to help women wear stilletos more comfortably. Whilst she agrees with the effects of muscle toning in the buttock region, she says that there must be compensation somewhere else and therefore her classes help with postural alignment.

Now as podiatrists we spend a lot of time dealing with and correcting the effects of postural malalignment. A personal trainer to some celebrities was quoted as saying that” the knees and metatarsals are put under strain, the hips are out of position. It can lead to long-term health risks.”

For me the evidence is there that the movement of the body’s centre of gravity forward causes increased loading and pressure. There is an increase in callus formation and the calf muscles shorten over time. This will lead to deformities of the toes. I agree however that exercises specifically to strengthen the intrinsic muscles of the foot will resist these deformations.

In “Walking on sunshine” they report on a New York sports therapist who holds classes for women to strengthen their foot muscles to cope with wearing high heels. Yamuna Zake also gives some good advice on foot care. She has been working with dancers for 25 years and those of you who struggled to get your (or your child’s) feet into the basic ballet positions without them falling flat will appreciate this. The essence of ballet is to be able to get your foot extended down from the ankle as far as possible and have almost 90 degrees of flexibility at the big toe joint.

So what’s the bottom line? Let me quote from the articles. ‘It’s a way to appeal to the male species. I have men who say heels have saved their marriage.’ Yamuna Zake says, ‘my husband is a freak about high heels. He thinks they’re very sexy.’ During my recent tutorials with Wits University medical students I was demonstrating the possible effect of rheumatoid arthritis on the way a person walks. I asked on of the girls to walk across the room in her high heels and then again barefoot to show the difference in patterns of healthy person. Guess what she said before walking barefoot? ‘Oh please I’ll walk like a boy!’

I wonder if walking in high heels will become an Olympic sport?

Fitting Children’s Shoes – Again!

Fitting children with shoes can be really difficult and is often unpleasant for all involved. That includes brothers, sisters and fathers hanging around nearby! This means that the responsibility for getting the correct usually lies with Mum. The trauma increases due to the fact that in South Africa, there are virtually no shops who know how to measure children’s feet and fit the correct size of shoe.

Some stores have had measuring boards available in the shoe section for some years, but using it was left to the customer. At the same time there was no guarantee that the size system on the board matched the size system of the shoes. Anyone who has bought sports shoes/trainers recently will know that they have three or four different size numbers on the tongue of the shoe. This is because the shoes are made in Asia for sale all over the world where the basic unit of measurement differs – including different centimetre units.

In an attempt to bring some order and science into the art of shoe fitting, the South African Podiatry Association (SAPA) has been working with various manufacturers and retailers to establish standards for footwear in this country. There is a committee of experts headed by a podiatrist who has done ground-breaking original research into the feet of South African women. This committee assesses lasts(the plastic shape around which a shoe is built) and footwear design, against a checklist based on this scientific research.

One retailer is Woolworths and if you buy your child’s shoes there – although you will have to fit them yourself – you will see certain styles have the SAPA approval logo on the green tag. Look out for other large retailers getting involved in 2008.

Do Your Children’s Shoes Fit?

Children’s feet need special care and attention and nothing is more important than selecting and fitting children’s shoes.

Oh yes, Happy New Year! The year is racing along already with Christmas holidays a fading memory. At present summer in Johannesburg also feels like a fading memory thanks to all the rain. With January came the start of a new school year and being too distracted with moving the practice I missed a great opportunity for ‘back to school tips’, but it’s never too late to review some of the basics. Especially as children grow so quickly and usually don’t tell you about short shoes because they get used to squeezed toes, or they hate the look of their prescribed school shoes. (Remember how long they stay as soft cartilage).Look at the page on Children’s Feet.

Did you have your children with you when you bought their shoes? Many parents buy based on size and take the shoes home to fit. [There are valid socio-economic reasons in South Africa, but it’s still a bad idea]. Also getting children into school shoes can be difficult if they are first-timers or have just spent six weeks barefoot or in sandals. (Or possibly Crocs!!)

Did you buy the shoes with your children wearing the socks they normally use for school?

Are the shoes stable and protective for those soft  vulnerable feet?  Is the sole firm with a flexible leather upper?How much synthetic material is there which is going to make the feet sweat? How do they fasten? Velcro is ‘cool’ but not often found on a school shoe. Doing up laces is currently ‘uncool’.

I doubt very much that you were able to check the fit of the shoes by having your child’s feet measured! A simple method of checking fit is to pour some powder into the shoes, put them on and have the child walk round the kitchen. Carefully take off the shoes and look inside for a centimetre of powder beyond the end of the toes. If you don’t see it then the shoes are probably too small.On the other hand never buy shoes too big so that they "can grow into them" or in the hope that the shoes will last a school year.

Children can outgrow shoes as quickly as new cars lose their value, so at the end of every school holiday check the fit of your children’s school shoes.

It could be that your "little Einsteins" are suffering irrepairable damage to their feet and you haven’t checked.

You And Your Feet

I’ve just come across an article I wrote a while ago for the South African Journal of Natural Medicine and thought it might be useful as a reminder as we embark on another year.

We need to take care of our lives, our relationships and our bodies as we renew our efforts in the New Year – and that includes our feet. 

Take a look now at You and Your Feet

Are Bunions The Bane of Your Life?

Bunions are among the most common and frequently most painful of conditions affecting the foot.

Remembering that your feet carry ALL of your weight ALL of the time that you are standing or walking then it is not surprising that the complex structure of your feet sometimes suffers re-alignment as they strive to accommodate our lives and activities.  Sometimes we do not help matters by forcing our feet into unsuitable or badly fitting shoes.

Go to the Foot Health Articles section for some useful advice on bunions.
