Brief summary: This study was a clinical trial to investigate the effects of Short Foot Exercise (SFE) and standard physical therapy on knee muscle tone, knee pain and function, balance ability, and quality of life in adults with flexible flat feet and knee pain.

Detailed description: This study aims to determine whether strengthening foot intrinsic muscles through SFE can reduce knee pain, improve muscle function, enhance balance, and improve quality of life in individuals with flexible flatfoot. Results may provide evidence-based rehabilitation strategies for managing knee pain in these patients.

* Health status: If you are a person without health problems and are trying to participate in the experiment

Exclusion Criteria:

* History of knee surgery: If you have had knee surgery
* Treatment history: If you have received physical therapy for knee pain in the 4 weeks before the start of the study
