Wide Width Shoe Sizing Guide for OEM Buyers

Foot width is one of the details buyers overlook most often when developing a new shoe program - and one of the most common reasons a "correct size" still doesn't fit right. At Mychonly, we work with multiple last widths across our men's and women's OEM programs, from Standard through Extra Wide, so partners can match a last profile to their target market instead of relying on a single generic fit.

The chart below shows how our width grading breaks down by size, from Standard Width up to 4E Wide, converted to millimeters for easier reference across different sizing systems (US, EU, UK, JP). Each width column corresponds to common manufacturer width codes (B/M, D/E, EE/2E, and so on), so our team and yours are working from the same reference point during development.

Why this matters for OEM buyers:

Different export markets skew toward different average foot widths - matching last width to your target market reduces return rates
Width grading affects last development cost and tooling - knowing your required width range upfront speeds up sampling
We can develop or adjust lasts to a specific width spec if your program needs something outside our standard range.

If you're developing a new style with us, let our team know your target width range early in the process - it's easier (and cheaper) to build it into the last from the start than to adjust after sampling.
