Flip-flops are some of the most comfortable and convenient kinds of shoes there are. They let you freely move your toes, aren't constrictive, and allow your feet to breathe. They can also be worn with almost any attire, and match most clothing styles. Unfortunately, wearing flip-flops can also be very dangerous. These sorts of shoes can harm your feet in more ways than you may think.

Although they are comfortable, constant flip-flop use can lead to problems with the ankles, hips, and lower back if worn on a long-term basis. This is because people walk much differently in flip-flops than they do in other shoes like sneakers. Their natural gait is being forced to change, throwing the body off and causing stress to different parts of the body. Flip-flops can also lead to problems in the arches of your feet, and pain in the balls of your feet. There is little to no support provided by flip-flops, so some parts of the foot undergo much more stress than normal.

Flip-flops can cause more obvious short term problems as well, like ankle sprains and frequent blisters. Because these shoes are relatively weak and can easily bend while walking, wearers are far more likely to trip and hurt their ankles. Flip-flops can also cause bad blisters, because their straps are constantly rubbing up against the foot. Additionally, someone wearing flip-flops is more prone to infections, due to the openness of the shoe. It very easy to scrape and cut your foot when wearing flip-flops because they offer little protection for the foot. If left untreated and uncovered, these same cuts can get dirtied and infected as flip-flops wearers walk around.

In order to avoid this, make sure to get a pair of flip-flops that will keep your feet as safe as possible. When looking to purchase flip-flops, you should check that the actual sole is sturdy and firm. The flip-flops are too floppy if the sole droops and wiggles a great deal when lifted off the floor. These will offer very little support, and may lead to other problems like tripping.

If you only purchase flip-flops made of high quality, sturdy materials, you won't have to worry about this. Although they will cost a little more, flip-flops made of these materials will last longer, and will protect your feet more so than a cheap pair of flip-flops. Also, make sure to buy from a reliable brand name. You can often find relatively cheap shoes from these companies, and once you have bought them you know they will last.

You can still wear your favorite flip-flops, just avoid wearing them every day of the week, or for extended periods of time. It is also recommended that you replace flip-flops every three or four months, in order to be sure that they provide maximum protection to your feet.

Orthotics is a medical field concerned with the design, manufacture and use of aids used to support weak limbs or direct the proper function of limbs, in this case the foot and ankle. Ankle-foot orthotics, or AFOs, are braces worn at the ankle that encompass some or all of the foot. Diseases that affect the musculature or weaken the affected area require AFOs to strengthen the muscles or train in the proper direction. Tight muscles that need to be lengthened and loosened also benefit from AFOs.

When we think of diseases that affect the musculature we think of the big boys: muscular dystrophy, cerebral palsy, polio and multiple sclerosis. We rarely think that arthritis and stroke can affect the musculature or that there are some who "toe in". But whatever trauma affects that musculature, there is a way to correct it. The orthosis helps to control range of motion, provide support by stabilizing walk, correct deformities and manage pain load. A podiatrist would be consulted for those who "toe in", for instance, or an arthritis sufferer whose ankles suffer through walking on the job or perhaps a victim of stroke whose musculature is wasting away and requires strength.

Before the advent of modern orthotic devices, it wasn’t uncommon to see polio victims wearing metal braces from mid thigh to the bottom of the foot, or children who "toed in" wearing metal braces around their ankle and foot. However, both designs and materials have improved dramatically, allowing for new levels of comfort, functionality, and appearance. Many orthotics are now made from plastics in the shape of an L and designed to fit inside a corrective shoe. These can be rigid, buckling at the calf and extending the length of the foot to support the ankle. This same design except with a hinged ankle provides support while walking by normalizing the gait. In the past boots lined with leather and fiberboard provided the rigidity needed for correction and support. Now corrective shoes are available with built up soles to correct the gait or manage pain by sharing it with another area when the foot spreads during walking.

The podiatrist would prescribe this orthosis in the rigid L shape because the foot moves on a hinge. If the hinge isn't functioning as intended due to an injury or malformation, the muscles tighten up, thus making it difficult to flex the foot. When we walk, the foot flexes and muscles stretch. This brace or AFO would support the ankle and musculature during flexion of the foot, in much the same way a knee brace works. Corrective shoes are for people whose feet hit the ground backward, causing tight muscles and arch problems. Wedges and rocker bars on the heels correct the step to heel first and rock onto the ball of the foot, resulting in relaxed musculature and strengthened ankles.

Appearance also counts when we consider a particular support device, especially if the item is intended for regular, daily wear. The L shaped orthotic is contoured to the calf and flesh-colored, fitting into a sneaker or dress shoe. As present, corrective shoes are more attractive than past models, enabling patients wear such devices with greater comfort and confidence.

A new trend in running and jogging has popped up recently, called barefoot running. Barefoot running is a popular and growing trend that is just what it sounds – running without shoes. Before deciding to do any running without shoes, it's best to understand how this kind of running affects the feet.

Running without shoes changes the motion of running. Most running is done by landing on the heel of the feet. Running barefoot requires a different way of running; in a barefoot stride landing is done on the front part of the feet. Because of this, the impact shifts from the heels to the front feet. Runners also shorten their strides to create a softer landing.

Running barefoot does have its advantages. When running and landing on the front feet, the impact on the feet and ankle is reduced, which may reduce the incidence of stress injuries. It strengthens muscles in the feet, and also strengthens muscles in the ankles and lower legs that aren't usually worked. Overall balance of the body is improved and there is greater sensory input from the feet to the rest of the body, making overall position and motion less stressful on the body. It has been found that in countries in which some of the population regularly wear shoes and some do not, numbers of foot and ankle injuries are much higher in those who wear shoes.

People hearing about barefoot running for the first time are skeptical about it, and there are good reasons for skepticism. Running barefoot certainly has its drawbacks, the obvious being no protection of the feet when running. This makes it likely that when runners land on sharp or rough objects,  scrapes, bruises, and cuts on feet will result. Blisters will form when beginning this kind of running especially, you may have plantar fascia problems. Landing on the front feet constantly also increases the risk of getting Achilles tendonitis.

So what can runners do to make barefoot running safe? It’s best to make a slow transition from running shoes to barefoot running. The body is used to wearing shoes so to slowly transition to bare feet, start by walking barefoot for a distance and then increase walking distance. Once the feet begin to adjust, try walking and then jogging and gradually increase the distance. If you have foot problems talk to the doctor first before attempting barefoot running. When starting out, it may also be helpful to begin by running on pavement or other consistent surfaces to avoid sharp or rough objects. Minimalist running shoes may also be an option, as they allow for many of the benefits of barefoot running while also protecting the feet from cuts and scrapes.
