Use a stratified random sampling method to select participants from different 9 states age groups, ethnic backgrounds to capture the diversity of foot sizes and shapes across the Indian population.

Determine an adequate sample size using statistical methods to ensure the results are representative and statistically significant.

Collaborate with students from the same institute located in different states.

Using ergonomic & anthropometric dimensions for collecting data.

Using ergonomics tools for measuring foot dimensions.

Clean the collected data to remove any inconsistencies or outliers. 

Perform statistical analyses (e.g., descriptive statistics, regression analysis, cluster analysis) to identify common foot size patterns, average measurements, and deviations. 

Categorize the foot shapes into typologies based on measurements and visual assessments. 

Based on the analyzed data, define size ranges for each measurement, ensuring coverage of the full spectrum of foot sizes and shapes by using mean & mode method.
