HOW BODY WEIGHT AFFECTS YOUR FEET

HOW BODY WEIGHT AFFECTS YOUR FEET
***January is Health Weight Awareness Month***

In addition to a slew of other health issues, carrying around extra weight on your body can cause some serious problems with your feet and ankles. As weight balloons, it will cause your body to shift how it distributes its balance, meaning that you have extra stress on your feet. Having your weight unevenly distributed can result in a lot of pain. This pain is present even when doing your simple, everyday tasks, like walking for a short distance.

1) Extra Weight Can Flatten Your Feet
Your feet have tendons and ligaments that bundle the bones together and hold them in place. Obesity can stress these ligaments and tendons, causing them to tear and break (Medical News Today). This can cause fallen arches and flat feet. When the arch of your foot lowers, it can cause your feet and every step to be painful. It lowers the effectiveness of their shock absorption, creating pain with every step. By using shoe inserts that can make each step more comfortable, you can stop this process in its tracks.

2) You Might Tear Your Plantar Fascia
An important part of your body is the plantar fascia, which connects the heel to your toes. Extra weight can cause stress during your daily activities. If you are overweight and are experiencing pain in your heels, you may have a case of plantar fasciitis. Investing in comfortable insoles for the inside of your shoes can help you avoid or correct this painful foot affliction.

3) Bone Spurs May Affect You
Carrying extra weight on your body can make your bones rub together. To prevent this from happening, your body may create some foot bone spurs. These are outgrowths from the bones in your feet (Mayo Clinic). Because of the stress that weight places on your joints, it is more likely that an overweight person will suffer from these. Being obese can affect them negatively, adding to the pain, stiffness, and tingling in your lower extremities. Talk to a doctor about effectively managing the pain caused by your bone spurs.

4) You Can Develop Localized Arthritis in Your Ankles
The Centers for Disease Control (CDC) reports (CDC.Gov).  that up to twenty percent of Americans suffer from arthritis. The two main forms of arthritis are osteoarthritis and rheumatoid arthritis. While arthritis can affect anyone, the instance of arthritis in people of larger weights is greatly enhanced. Arthritis in the ankles is a form of osteoarthritis. It happens when your cartilage wears down, that flexible and durable tissue that protects your bones from rubbing together at the joints. Obesity can cause your cartilage to wear away faster. While osteoarthritis is a stress injury, rheumatoid arthritis is an autoimmune issue where your body attacks its own joint tissue. Studies have shown that chemicals found in adipose tissue (fat) can cause rheumatoid arthritis to get even worse (Arthritis Foundation).

5) Diabetes Can Greatlyt Affect the Health of Your Feet
In addition to your weight distribution, your feet need adequate circulation and blood flow to stay healthy. Diabetes, which disproportionately affects those of larger weights, can cause a reduction of the flow of blood to your feet. If you develop sores on your feet, they can quickly become ulcerated and difficult to treat. Numbness in your extremities is an important reason to seek the aid of a medical professional. Over 70,000 amputations are done of feet and lower legs every year. It is important to your health to stay up to date on all medications and get a regular check up to catch issues before they get worse.

With so many issues that can affect your feet, it is no surprise that you will want to find relief. Give yourself appropriate and adjustable arch support and minimize foot pain by using orthotic insoles by SelectFlex®.

FOOT BIOMECHANICS

Characteristics & Anatomy Of The Foot

The feet are the foundation of support for the pelvis, spine and lower body. They provide the necessary stability to perform daily activities. The foot and ankle form a complex system which consists of 28 bones, 33 joints, 112 ligaments, controlled by 13 extrinsic and 21 intrinsic muscles. The foot is subdivided into the rear-foot, mid-foot & fore-foot and central to the success of the pedal foundation is its “arched structure”. The Arched Structure is a complex of three bony arches: the medial longitudinal arch, the lateral longitudinal arch and the anterior transverse (metatarsal) arch.(Physio-Pedia)

Arches of Foot

The 3 arches of the foot allow the foot to absorb downward forces and act as a rigid lever during gait propulsion:

  • Medial Longitudinal Arch: The most obvious arch is seen along the medial aspect of the foot. The navicular bone forms the "keystone" of this large and long arch, which is supported primarily by the plantar fascia and spring ligament. The muscles of the foot and lower leg do not provide support for the medial arch, except during toe-off when walking or while standing on tip-toe.
  • Lateral Longitudinal Arch (LLA): This arch is located along the outside of each foot and relies much less on connective tissues for its support. For this reason, proper function of the lateral arch is extremely dependent on the alignment of the cuboid bone, which is frequently found to be in need of adjustment. Proper support for this arch is at least as important as for the other two, but is surprisingly absent in many orthotics.
  • Transverse (Metatarsal) Arch: This arch extends from the metatarsal heads back to the tarsal bones, and runs from the medial to the lateral sides of the foot. At its most anterior portion, the metatarsal heads contact the ground. Poor function and loss of this arch will often result in a build-up of thick callus underneath the metatarsal heads. Recurrent "dropped" metatarsal heads and/or irritation of one of the interdigital nerves (a "Morton's neuroma") is also a good indications that this arch is not being supported properly by the plantar fascia(Dynamic Chiropractic)

Static and Dynamic Support With Orthotics

The structural design of the three-arched plantar vault is very good at supporting weight and carrying heavy loads, while remaining flexible. During normal standing, the load of the body is balanced over the center of the foot, anterior to the ankle. This places the greatest amount of load at the apex of the three arches. This force is then distributed along the "buttresses" of the arches to the heel (which bears 50 percent to 60 percent of body weight) and the metatarsal heads (which bear 40 percent to 50 percent of body weight). Loss of this configuration will result in abnormal force concentrations, which will eventually cause degenerative and symptomatic clinical conditions. (Foot Education) 

During gait, the foot undergoes substantial changes. The arches and connective tissues must sustain the stress of heel strike, then adapt to the ground during stance phase, and finally become a rigid lever to provide an efficient push-off. This must all occur in a coordinated manner, with no glitches or hang-ups. The foot must permit a smooth transfer of the body's center of mass over the leg to conserve energy and keep the work expenditure to a minimum. The heavier a patient is, the greater the stresses on the feet and ankles.

Collapse or dysfunction of any of the arches needs to be addressed with flexible yet stabilizing orthotics that will support the patient's foot both during standing (static support) and throughout the gait cycle (dynamic support), while controlling the impact forces. There is one actual insole that provides “Dynamic” support called SelectFlex which uses a patented arch lifting technology called the PowerLift Arch. The PowerLift Arch provides the wearer with 3 levels to support the arch with dynamic alignment with every step. This unique arch technology dynamically lifts your arch into a comforting sine wave motion that provides up to 89% more arch support with every step.

How is Energy Return Important? [StatIc vs. Dynamic Insoles]

Energy Return is important for foot health and mobility. There are many types of Energy Return provided by footwear and insoles.

Most footwear and insoles are basically static, absorb and cushion energy but do not return significant energy nor dynamic alignment.

The best footwear and insoles generate greater alignment with the body, joint health and more energy at the end of the day from easier movement and less pain from their support of the body.

The most competitive footwear will propel or push you forward more efficiently when running, while the best insoles create and maintain support for your lower extremities.

The Holy Grail for marquee footwear manufacturers is to provide quantifiable energy return for their customers feet that produce quicker running times and higher performance.

NIKE React Foam technology was recently used in their marathon running shoe soles with a carbon fiber footpad. Nike achieved the Holy Grail of true 13% energy return while providing 4% propulsion for faster marathon times. Nikes high performance foam uniquely absorbs foot strike energy on the down step and releases it during toe-off with marathon setting results.

Conversely, soft materials are great at absorbing energy but are very inefficient at returning energy. This is often found in insoles that use foam to absorb impact, cushion and support the foot but are unable to return meaningful energy.

Protalus foam insoles do a good job of stabilizing the heel with their triplanar technology but do NOT return energy to the foot. Dr. Scholls inserts has the same foam limitation without the stabilising heel.

Foam is comprised of a matrix of thin walled air cells packed together within a polymer form, that individually begin to break down and compress over time, reducing the impact, cushioning and support they were originally designed to provide.

SelectFlex is an entirely new type of dynamic energy returning insole on the market that just won the ISHN Best Protective Footwear category for 2020.

SelectFlex insoles use a patented energy returning arch lifting technology called the PowerLift Arch. The PowerLift Arch provides the wearer with 3 energy return levels to support the arch with dynamic alignment with every step.

This unique arch technology dynamically lifts your arch into a comforting sine wave motion that provides up to 89% more arch support with every step. SelectFlex recently completed an in depth study at a major University. The revolutionary Certified Lab Tests & Performance Benefits measured, sets SelectFlex apart from static footwear and insoles.

For the first time, there is finally an insole that dynamically returns energy to the foot and the arch by lifting it into comforting re-alignment!
