What is shoe width eeee?

Excuse me, could you please clarify what you mean by "shoe width eeee"? As far as I'm aware, shoe widths are typically measured in different scales, such as A, B, C, D, E, etc., and I'm not familiar with "eeee" as a standard width designation. Is this a specific brand or model of shoes that uses this measurement? Or perhaps there's a typo in the question? Could you provide more context or clarification? Thank you.
