What is the best datatype for storing detail of your shoe size?

The best datatype for storing shoe size details is typically a string or a decimal type, depending on the level of precision needed. A string can accommodate various formats, such as numeric values with letters (e.g., "10.5", "M", "7.5W"). If you want to store only numeric values without the need for additional characters, a decimal type can be used to ensure precision for half sizes. Ultimately, the choice depends on how you plan to use or display the shoe size information.
