How wide is 4E in inches?
I'm curious to know, could you please clarify the exact measurement of "4E" in inches? Is this referring to a specific dimension in a technical specification, or perhaps a size notation for a product like shoes? Without further context, it's difficult to provide an accurate answer. Could you please elaborate on the context in which "4E" is being used? This would help me to give you a more precise and informative response.
