- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- mRSF-ESF (Type: EXPERIMENTAL): Study participants in Arm 1 will first receive the Modified running specific foot (mRSF) and then the Energy storing foot (ESF). Outcomes will be assessed (in each condition) after 1 month of use. Order of interventions will be randomly assigned.
- ESF-mRSF (Type: EXPERIMENTAL): Study participants in Arm 2 will first receive the Energy storing foot (ESF) and then the Modified running specific foot (mRSF). Outcomes will be assessed (in each condition) after 1 month of use. Order of interventions will be randomly assigned.

Based on this trial design, predict the completion outcome and termination type (if applicable).
