General Information

General information on prosthetic feet

Designing prosthetic foot systems is challenging. It’s very difficult to reproduce the complex workings of the human foot and ankle. Ideally the foot will be light because its weight is added to the rest of the prosthetic leg. If the foot is too heavy and the suspension of the prosthesis is not appropriate, the connection to the socket and your limb will be affected and also the overall function of the prosthesis.

A good prosthetic foot should also be strong, as it will be taking on large forces and torque as you walk and run. Feet must also be small enough to fit within a foot shell, a cosmetic covering for the prosthetic foot, and thus fit within a shoe. Being light, strong and small whilst still remaining functional and durable is the challenge.

Early designs for prosthetic feet were often a solid piece of wood. A similar design, the SACH (solid-ankle-cushioned-heel) is still in use because of its sturdy function. It is especially useful for individuals with lower activity levels. A SACH foot typically has a rigid inner structure (wood or plastic) surrounded by a compressible foam cosmetic shell.

Today’s more sophisticated feet add more functions and are secured inside a cosmetic shell. Most people never see their prosthetic foot without this exterior shell. The cosmetic shell stretches around the prosthetic foot and serves two purposes:

  • It makes your prosthetic foot look like an anatomical foot.

  • It fits snuggly in your shoe.

What’s inside the shell can vary dramatically. Prosthetic feet are designed to meet the needs of your lifestyle and activity level. Here are some factors to consider.

Materials

The materials in a prosthetic foot differ by activity level. Wood, plastic and foam are usually found in feet designed for individuals who have low activity levels and require stability. Lightweight carbon fibre feet meet the functional needs of active individuals since they are built for shock absorption and energy efficiency.

Comfort

A prosthetic foot has to feel good for you to meet your activity goals. Comfort allows you to be more active and the function of your prosthetic foot directly affects comfort.

Function

Prosthetic feet are designed to mimic a human foot at a specific activity level. For lower activity individuals, a prosthetic foot is designed to provide stability and balance. For those who are most active, a prosthetic foot must mimic the natural foot during the act of walking. It must act as a shock absorber as you strike your heel to the ground, adapt to uneven terrain, provide a smooth rollover from heel to toe, and provide a rigid lever for propelling forward when you finish your step (“toe-off”).

Multi-axial motion

Some prosthetic feet are designed to mimic the ankle which allows the foot to move in multiple planes. Multi-axial capability in a foot allows the foot to absorb varying terrain by moving in all directions. These motions are forward to back, side to side and rotation around the ankle. Multi-axial motion is needed to walk comfortably and confidently on uneven ground where your foot must adapt to whatever it encounters.

Energy storage

A carbon fibre foot is able to store and return energy while walking and literally gives you a spring in your step. The carbon fibre acts as a spring which compresses as you apply weight and then propels you forward as you roll off the toe of the foot when the energy is returned. Some prosthetic feet have one spring in the heel and a second spring in the forefoot: just what you need for walking at different speeds, running, climbing hills or descending stairs with a secure, confident stride. With carbon fibre, the longer the spring, the more energy it can store and the more responsive the foot will be.

Selecting a Prosthetic Foot

How you and your Prosthetist select the right prosthetic foot for you

Choosing a prosthetic foot that best suits your personal requirements, needs and goals is a complex task. Your Prosthetist is an expert in this field. Thanks to his education, experience and biomechanical knowledge, he will choose the prosthetic foot that helps achieve the best possible fitting outcome for you individually. The information provided in this section only serves as a guidance. Please contact your Prosthetist if you have more detailed questions.

Amputation Level

Your level of amputation will be one of the first things that needs to be looked at when choosing the components in a prosthesis. An above knee amputation requires a prosthetic knee joint and the type of knee joint will help to define the appropriate prosthetic foot. This is where your Prosthetist will assess the functions of the prosthetic knee joint and recommend an appropriate prosthetic foot. Because the natural knee joint is intact after a below knee amputation, your Prosthetist will consider factors like length of the residual limb, strength and range of motion when recommending an appropriate prosthetic foot.

Activity Levels

Manufacturers categorise prosthetic feet by the user’s activity level – also called mobility grade. This means that not every prosthetic foot can be used by every user. Selecting a prosthesis that matches your activity level will maximise your mobility and your quality of life. Here are some very basic indications for identifying your activity level. If you are on the border between two activity levels, your Prosthetist will consider multiple products to assess the one that is best for you.

Activity Level 1

The amputee has the ability or the potential to use the prosthesis for transfers or for the purpose of moving slowly on level floors. The amount of time and the distance the amputee can walk are seriously limited due to his or her condition.

Therapy goal:

Restoring the ability to stand and to walk indoors to a limited degree.

Activity Level 2

The amputee has the ability or the potential to walk slowly with the prosthesis and to negotiate low environmental obstacles like curbs, single steps or uneven surfaces. The amount of time and the distance the amputee can walk are seriously limited due to his or her condition.

Therapy goal:

Restoring the ability to stand and walk both indoors and outdoors.



Activity Level 3

The amputee has the ability or the potential to walk with the prosthesis at a medium to high speed as well as at different speeds and simultaneously overcome most natural obstacles. He or she is also capable of walking outdoors and engaging in professional, therapeutic and other activities that do not subject the prosthesis to above-average mechanical strain. There may be an increased need for safety due to secondary circumstances (additional disability, special living conditions) combined with medium to high mobility demands. The amount of time and the distance the patient can walk are only mildly restricted compared to individuals without disabilities.

Therapy goal:

Restoring the ability to stand and to walk indoors and outdoors with only mild restrictions.


Activity Level 4

The amputee's ability or potential to walk with a prosthesis is similar to that of the unrestricted outdoor walker. The amount of time and walking distance are not limited. Moreover, due to the high functional demands, a high degree of shock, tension and distortion can occur.

Therapy goal:

Restoring the ability to stand, walk and move about both indoors and outdoors without any limitations.



Body Weight

Prosthetic feet are designed for a specific weight range. To ensure that a prosthetic foot performs well for you, your Prosthetist will choose one suited to your weight class.

Build Height

Prosthetic feet vary in height. We call the height of a prosthetic foot build height. Your height and the length of your residual limb as a below knee amputee will determine the space you have for a prosthetic foot and what is the appropriate build height for the prosthetic foot. As an above knee amputee, the length of the prosthetic knee joint will be an additional factor to consider for the build height of the prosthetic foot.

FirstSpiritExport,OBISCM-1557,web_site,prosthetics_2,lower_limb_1,triton_side_flex

Foot Size

Like human feet, prosthetic feet differ in length/size. Prosthetic feet are sized by cm rather than standard shoe sizes. Every foot is available in a specific range of sizes. There are prosthetic feet that come in sizes for children while others are even sized for large adults. Ottobock running blades and speciality sports feet often have a a single size.

Personal Factors

Apart from all the technical selection criteria, your Prosthetist will keep in mind your personal needs, living situation and goals when choosing a prosthetic foot for you. These factors might be the desire to participate in sports activities or the ability to paint your toenails. These are of great importance because your prosthetic foot should feel like an extension of yourself.

FAQs

Frequently Asked Questions

Where can I be fitted with a prosthesis?

The prosthetic fitting can be done at your local NHS or private prosthetic clinic. More information about our private clinics can be found here.

How do my Prosthetist and I select the right prosthetic foot for me?

Together with you, your Prosthetist will choose the prosthetic foot that best fits your individual habits, preferences and needs – based on your amputation level, mobility grade, your lifestyle and further criteria. The better informed you are during this process, the better you can tell your Prosthetist what you really need and the more actively you can participate in your fitting. But be sure that your prosthetist will always choose what’s best for you.

Can I test different prosthetic feet?

What if I realise after some time that I don't feel comfortable with the prosthetic foot?

Yes, you can test different prosthetic feet. Many clinics offer trial fittings, just talk to your Prosthetist. The trial fitting takes place over a predetermined period of time.

60 day satisfaction guarantee – We’re so confident that you’ll be satisfied with the Taleo foot range, that if you decide you’re not happy, we will happily take the foot back, no questions asked!

Who pays the costs for my prosthetic fitting?

Some prosthetic feet are available free through the NHS, if you are getting treatment through a legal case the insurance may cover the costs. If neither of these options are suitable for you then you may need to purchase the foot through a private clinic.

Are prosthetic feet waterproof?

Some prosthetic feet are waterproof. Others are not. Some are fully waterproof against fresh, salt and chlorinated water, while others might only be weatherproof. It depends on the prosthetic foot. If it is important for you to have a prosthetic foot that is waterproof, please talk to your Prosthetist to find the best solution for you.

Do I need to wear special shoes with a prosthetic foot?

In general no. Our prosthetic feet are delivered with a footshell that is based on the shape of a natural foot so that it is possible to wear most common types of shoes. Many foot sizes come in both a slim and normal version to match your natural foot as closely as possible. Some feet and footshells have a split between the big toe and second toe that makes it possible to wear flip flops. The Meridium prosthetic foot even features automatic heel height adjustment.

Are prosthetic feet suitable for sports activities?

Most of our prosthetic feet provide you with support for a wide range of everyday activities. Some are also perfectly suitable for occasional light sports activities such as badminton or playing frisbee. However, if you want to engage in regular and demanding physical activities or sports that involve running or jumping, an Ottobock sports foot might be more appropriate.

Can I walk around barefoot with my prosthetic foot?

With some prosthetic feet it is possible to walk around barefoot for short periods indoors. Your Prosthetist will give you useful advice.

Does my prosthetic foot have to be serviced regularly?

This depends on what kind of prosthetic foot you have. Our carbon and sports feet don’t need regular service. Our Empower and Meridium mechatronic feet have to be serviced every two years. During this time, you will get a loaner foot.

How long can I use my prosthetic foot?

Prosthetic feet are tested to two million gait cycles per ISO standards. Depending on your activity level and how much you use your prosthesis, we recommend replacing the prosthetic foot every 2-3 years.
