What is the average shoe size for a 5'11 male?

I'm curious, could you please elaborate on the factors that contribute to determining the average shoe size for a 5'11 male? Is it purely based on height, or do other factors such as age, ethnicity, and genetics play a role? I'm interested in understanding the nuances behind this measurement and how it can vary among individuals. Additionally, is there a reliable source that provides a definitive answer to this question, or does it vary depending on the population being studied?
