Quick Answer
A prosthetic foot replaces part or all of a natural foot after amputation, helping you walk and stay active. The most common reason for foot amputation is diabetes-related foot problems. A prosthetist custom-makes it over several weeks, and getting used to it can take months. Most prosthetic feet last three to five years.
What the research says
Powered feet lowered the energy cost of walking: across 15 studies of 141 people with below-knee amputation, feet with powered ankle motion reduced the energy needed to walk compared with energy-return feet, which didn't beat simpler feet on level ground (Hafner BJ et al., PM&R, 2022) [2]
Energy-return and powered feet gave more push-off: a review of 28 studies found push-off power rose with walking speed for energy-return and powered feet, but not for basic SACH feet (Müller R et al., PLOS One, 2019) [3]
Key takeaways
A prosthetic foot replaces part or all of a missing foot.
Diabetes-related problems are the most common cause of foot amputation.
Types range from simple to computer-controlled.
A prosthetist custom-makes each foot.
Most prosthetic feet last three to five years.
What is a prosthetic foot?
A prosthetic foot is a type of prosthesis. It attaches to a custom socket on your residual limb using suspension systems such as vacuum suction or a pin lock. Learn more about prosthetic feet. Sources: [1]
Who needs one
It can restore mobility, independence and quality of life.
Diabetes-related foot problems, the most common reason.
Trauma.
Infection.
Tumors.
Peripheral artery disease. Sources: [1]
Types of prosthetic feet
Partial-foot options are available too.
Type | Key feature |
SACH | Simplest; solid ankle, often temporary |
Flexible keel | Flexes a little for uneven ground |
Axial | Mechanical ankle; durable and stable |
Hydraulic | Fluid for smooth motion and shock absorption |
Energy-return (ESAR) | Carbon fiber returns energy; common for sports |
Microprocessor | Sensors adjust automatically; battery powered |
Specialty | Running, swimming, showering and other activities |
Partial-foot options include shoe inserts, ankle-foot orthoses, silicone prostheses and carbon fiber footplates. Sources: [1, 2, 3]
Getting a prosthetic foot
The whole process takes several months.
Meet with a prosthetist to discuss your needs and goals.
Your limb is measured and molded.
Your foot is custom-made over several weeks.
You learn how to use, clean and care for it.
Physical or occupational therapy helps with daily activities. Sources: [1]
Risks and challenges
Pressure sores.
Skin irritation from sweat.
Balance problems or muscle strains.
Mechanical failures.
Microprocessor feet need nightly charging and must stay dry. Sources: [1]
Living with a prosthetic foot
Don't sleep with your prosthesis on.
You can drive; hand controls can be added to a car.
A counselor or support group can help with the emotional adjustment.
Adjusting can take several months. Sources: [1]
Outlook
Most prosthetic feet last three to five years, depending on use. Your fit may need adjusting sooner as your residual limb changes shape. Your prosthetist can help solve any problems. Sources: [1]
Conclusion
A prosthetic foot can restore your mobility and independence after amputation. Choosing the right type with your prosthetist and working with therapists help you walk safely and confidently.
