The prosthetic foot makes a difference for your fitting success

The relevance of the prosthetic foot

The prosthetic foot makes everything else possible. Whether you‘re an above or below knee amputee, the quality and performance of your whole prosthesis will be impacted by the quality and performance of the prosthetic foot.

With a wide range of Ottobock prosthetic feet you can be sure that together with your O&P professional you will find the one prosthetic foot fitting to your personal needs. Whether it is a foot made out of carbon or it is a microprocessor-controlled foot – our whole portfolio is based on the same idea: building a foundation. We take our responsibility seriously. When choosing a prosthetic foot from Ottobock, you can be sure that each one is designed with passion, in compliance with highest quality standards and always with your needs in mind.

Your suitable prosthetic foot

How you and your O&P professional select the right prosthetic foot

Please note: Choosing a prosthetic foot that best suits your personal requirements, needs and goals is a complex task. Your O&P professional 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 serve as a guidance. Please contact your O&P professional if you have more detailed questions.

Personal factors

Apart from all the technical selection criteria, your O&P professional will keep in mind your personal needs, living situation and goals when choosing the foot prosthesis. 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 be like an extension of yourself.

Amputation level

Your amputation level will be one of the first things that needs to be looked at when chosing the components in your 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 O&P professional 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 O&P professional will consider factors like length of the residual limb, strength and range of motion when recommending an appropriate foot prosthesis.

Activity level

Manufacturers categorize 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 maximize your mobility and your quality of life. If you are on the border between two activity levels, your O&P professional will consider multiple products to assess the one that is best for you.

Body weight & Foot size

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

Like human feet, prosthetic feet differ in length and 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 specialty sports feet often have a a single size.

All about prosthetic feet

Being light, strong, and small, and yet functional and durable is the challenge.

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. 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 footshell, a cosmetic covering for the prosthetic foot, and thus fit within a shoe.

Comfort & Function

A foot prosthesis has to feel good for you to meet your activity goals. 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”).

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.

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.

The 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 snugly in your shoe.

Frequently asked questions

Together with you, your O&P Professional 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, the better you can tell your O&P professional what you really need and the more actively you can participate during your fitting process. But be sure that your technician will always choose what’s best for you.

Reimbursement depends on your individual personal situation, country of residence and insurance company. The price of prosthetic feet generally rises with activity level because additional functionality translates to more expensive materials and designs. Insurance companies often will cover a more expensive prosthesis if it will enable you to increase your activity level, work a longer day or take fewer days off. Your O&P professional will support you during the reimbursement process.

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 variant 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 sandals. The Meridium prosthetic foot even features automatic heel height adjustment.
