Barefoot Running
Barefoot running is becoming a popular running trend that has been permeating through the running and jogging communities. The act of running without shoes changes more about the motions of your stride than you may think, and choosing to run without shoes is not the only adjustment you will have to make.

Whenever you run normally, with shoes, your heel strikes the ground first as you land while you roll over the ball of your foot and push off with the front part and toes. Barefoot runners actually land on the front part of their feet and not their heels, shifting the impact from the back to the front of the foot. In order to do this safely and without much injury, runners need to reduce their stride to create softer landings.

One of barefoot running’s biggest advantages is the reduced risk of injury. Landing on the front of your foot with a reduced stride lessens the stress placed on the back of the foot, heels, and ankles. It also works out many muscles in the feet, ankles, and lower legs that you do not normally get to strengthen because of the different motion.  Your posture and balance are also improved with barefoot running, as is your sensory input from your feet to the rest of your body. Studies have shown that ironically, countries that have large populations of people who do not wear shoes every day are at lower risk for foot and ankle injuries and complications.

However, there is still some skepticism behind barefoot running because of some disadvantages it brings. One of these is the complete lack of protection for your feet while running. Bruises, scrapes, cuts, and even blisters can easily form when you have no protection from sharp or rough objects on the ground. Landing on the front of your feet can also cause Achilles tendonitis because of the overuse of the Achilles tendon.

Despite this, barefoot running can be made safe and enjoyable if you make a slow transition from your normal running routine into barefoot running. You cannot simply start the activity out of the blue one day, but instead gradually work your way from walking to jogging to running, increasing the distance each time. It is also recommended to start off on flat, even surfaces that do not contain sharp or dangerous objects because your feet are now unprotected. Minimalist running shoes are a great middle ground to start with because they combine the protection of shoes with the fit and feel of barefoot running.


Effect of High-Heels on the Feet
For hundreds of years, women have been wearing various kinds of high-heels for mostly aesthetic reasons. Women who wear high-heels appear to be taller and to have longer and thinner legs, and the wearer’s gait and posture changes. Though high-heels have had an association with femininity and have kept them popular over the years, there are definite health problems caused by wearing them too frequently.

The motion of the ankle joints is limited when heels are worn. The ankle joint is very important to the body when it comes to walking. Because of their location, these joints have a great deal of weight put on them. Thus, it is very important to keep them as healthy as possible. The Achilles tendon is the main tendon in the ankle. Wearing high-heels too often, studies have shown, can cause the calf muscle and Achilles tendon to shorten and stiffen, which can cause problems when shoes without heels are worn.

By putting a great deal of pressure on the ball of the foot, by forcing the toes into a small toe box, high-heels can cause or may worsen many foot problems, such as corns, hammertoe, bunions, Morton’s neuroma and plantar fasciitis.

Not only does wearing very high-heels regularly have negative effects on the feet, the rest of the body can suffer as well. The knees, one of the most important joints in the entire body, can be affected by wearing high-heels.  High-heels causes the knees to stay bent all the time. Also, it can cause them to bend slightly inward as well. Doctors believe that women can suffer from osteoarthritis later in life because of constantly walking like this. By limiting the natural motion of the foot during walking, high-heels also cause an increased in stress on the knees.

Similarly, the back may also be affected by high-heels because it causes the back to go out of alignment. If high-heels are worn constantly, the spine’s ability to absorb shock can cause continued back pain. They can compress the vertebrae of the lower back, and can overuse the back muscles.

However, this is not to say that high-heels can never be worn. If worn occasionally, they will not cause serious problems. They should not be worn every day in order to avoid the long-term physical health problems of the feet, knees, ankles, and back like mentioned above.


Blisters on the Feet
Blisters are a common ailment of people who wear shoes that are either too tight or rubbed up against their feet in the wrong way while wearing them. In order to better understand how they are formed and what treatment should be used for them, you have to start with the basics of what a blister actually is.

A blister on the foot, or any other part of the body for that matter, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery like fluid that should not cause any concern. However, blisters can fill up with blood if they are deep enough and even pus if they have become infected with bacteria.

Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time for example, or when your shoes simply do not fit you properly. They also form faster and easier if your feet are moist, so keeping them dry and clean is a preventative step you can take to avoid getting blisters.

Preventing infection should be the number one concern when treating blisters, as well as alleviating the pain they can cause. Using a band aid to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop, or you can take a pin and try to pop it yourself.

If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics might need to be taken in order to completely eliminate the bacteria inside the blister, and that needs to be prescribed by a doctor.

However, one of the best ways to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a band aid to an area you think might get a blister before one pops up is another way you can prevent them.


Hyperhidrosis of the Feet
Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that is not onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.

Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.

Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.

The symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the materials, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.

If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.

If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.

A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.
