Shoe conversions are approximate. Brand, model, width, last shape, and sock thickness can change the best size.
Shoe width guide
Width matters when the length conversion looks right but the shoe still feels tight or unstable.
| Width | Common men's label | Common women's label | Fit sign | What to do |
|---|---|---|---|---|
| Narrow | B or N | AA-B | Feet slide forward less, but sides feel tight | Try standard width first only if brand runs wide |
| Standard / Medium | D or M | B or M | Most default shoe listings | Best starting point for conversion charts |
| Wide | 2E or W | D or W | Toes or forefoot feel compressed | Use wide width instead of sizing up only for width |
| Extra wide | 4E+ or XW | 2E+ or XW | Ball of foot spills over midsole | Prioritize brands with extended-width models |
Width labels vary by brand. If length is correct but the forefoot feels tight, a wide width is usually better than sizing up.
Brand fit comparison notes
Use these notes as shopping guidance, not as official brand sizing. Always compare the product page chart before ordering.
| Brand | Common fit pattern | Best conversion check | Caution |
|---|---|---|---|
| Nike | Often athletic and performance-fit | Start from CM/JP foot length, then check model reviews | Running and lifestyle models can fit differently |
| Adidas | Often true-to-size to slightly roomy by model | Compare UK/EU label and CM when available | Unisex models may use men's US as the primary label |
| New Balance | Strong width options on many models | Choose length first, then width | Width can solve fit better than going up a half size |
| Crocs | Roomy clog fit in many classic styles | Expect more toe-box space than sneakers | Check whether the style is roomy, relaxed, or standard fit |
Brand pages should avoid implying official affiliation. Treat these as independent size-chart references and link users back to generic conversion tools.

FAQ
Is this an official New Balance size chart?
No. This is an independent size-chart guide. Check the product page chart for the exact model and width.
Do New Balance widths matter?
Yes. Width options can solve fit issues that a length-only conversion cannot.
Should I size up in New Balance?
If length is short, size up. If only the forefoot is tight, try a wider width first.
