sizes dont upload to corresponding men/women conversions

Shopify Discussion

Topic summary

Shoe retailer needs cross-gender/age size mapping in Shopify so equivalent sizes appear when customers shop by size. Current issue: men’s/women’s/youth variants don’t surface across their equivalent conversions (e.g., Youth 3.5 should also appear as Women’s 5W), leading to missed results in size-based browsing.

What’s desired:

  • When selecting a size, show all equivalent sizes (e.g., selecting 7 also shows 8.5W), as demonstrated by another Shopify store in provided screenshots.

What’s been tried/advised:

  • Shopify support suggested an app or custom coding, but available apps found are only size charts (static), not functional variant mapping for filters or listings.

Needs/Questions:

  • How to implement automatic cross-size mapping in collections/filters/product pages (app recommendation or coding approach).

Artifacts:

  • Images/screenshots are central to understanding the desired behavior and UI.

Status:

  • Unresolved; seeking practical solution or implementation guidance.

We have an online and brick mortar shoe store that sells men, women & childrens shoes.

The problem: Our Men/Womens shoes are not uploading to the corresponding size conversions For example we have a size 3.5 in youth however that conversion is equivalent to a size 5W (Womens)..

When customers shop by size, we would like those conversions to populate. The shopofy advisors are telling me to achieve this it may be an app or coding solution however the apps are sizing charts..

Would appreciate help!

The photos show an example of another shopify store that does this correctly.. You can see i’m on the size 7 however it also displays size 8.5W…
