Trial Title: Feasibility Study to Evaluate a New Energy Storage and Return Prosthetic Foot

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~1. Person is 18 years or older.~2. Currently uses an energy storage and return foot.~3. Person has been a unilateral transfemoral (TF), or transtibial (TT) amputee using a prosthesis for at least 1 year.~4. For TF amputees, the person must be wearing an Ottobock Microprocessor-controlled Knee (MPK) with a compatible prosthetic foot~5. Person weighs ≤ 275 lbs (125 kg) size 26-27cm or ≤ 220 lbs (100 kg) size 24-25cm~6. Person is a K3 ambulator based on Medicare Functional Classification Level (MFCL).~7. Prosthetic foot size is 24 to 27 centimeters.~8. Socket Comfort Score of at least 7~9. Ability to read and understand English~10. A person is able and willing to give consent~Exclusion Criteria:~1. Current prosthetic foot is too old or worn out as assessed by the CPO.~2. TT subject with currently fit with a Proflex XC or TF subject currently fit with a Taleo.~3. Patient is pregnant or planning to become pregnant.~4. Person who has a life-threatening medical condition (i.e. terminal cancer, severe heart disease).~5. Person has conditions that would prevent participation and pose increased risk (e.g. unstable cardiovascular conditions that preclude physical activity such as walking, problems with vestibular system, etc.).~6. Ulceration or skin breakdown of the residual limb.~7. Person currently has residual limb issues that significantly reduce their ability to load the prosthesis.
