High Heel Size Charts: What Wholesale Buyers Should Confirm

1. Identify exactly what the chart describes

Start with the style code and the chart version or date. Ask whether the table applies to the selected construction and available size range, or is only a general reference. Keep the original size designation beside any proposed retail equivalent. Do not replace a supplier’s CN, EU, UK or US label with another system simply because the numbers look familiar.

Ask what every length column measures: the foot, the last used to shape the shoe, or an internal dimension of the finished shoe. Record the unit and measurement method. These are different objects, so a value described only as length is ambiguous. If a supplier cannot yet confirm a field, leave it pending instead of copying a measurement from another style.

2. Use conversions as a reference, then verify the product

ISO 19407:2023 presents conversions between major sizing systems using foot length as the reference. Its public summary describes the adult tables as guidance, reflecting differences in how sizing systems developed. That supports a practical buying rule: retain the original size information and verify any proposed conversion against the actual footwear. A standard reference is not evidence that a particular product was assessed to it.

For a private label range, agree which size system will appear on the shoe, box and online listing. If you display more than one system, ask the supplier to confirm the complete mapping in writing. Do not publish a universal conversion chart across your catalogue until you have established which styles it covers and how exceptions will be shown to shoppers.

3. Prepare a useful fit sample review

Confirm the sample style, marked size, colour and version before reviewing it. Record the wearer’s measured foot information, the socks or hosiery used and the review conditions. Describe observations separately for the left and right shoe. Feedback such as tight across the forefoot is more useful than a bare request to make it bigger, especially when the heel already feels loose.

A colleague who usually buys one size cannot represent every customer in that size. Agree a review plan suited to your intended market, including which sizes and foot profiles need assessment. Where the buying risk warrants it, use a qualified footwear fit assessor. Do not promise a comfort level or a reduction in returns from a short informal fitting alone.

4. Check shape and retention as well as length

SATRA explains that fit depends on the foot, the last and the finished footwear, with design and manufacturing also affecting the result. For high heels, organise feedback around the toe area, forefoot, heel hold and any straps. Note where pressure, sliding or a gap occurs. A photograph can locate the concern, but it cannot establish how a shoe fits during wear.

Record fit observations separately from appearance decisions. A requested change to a pointed toe, strap position, lining or padding should identify whether another sample review is needed. Ask the supplier which dimensions or components would change and which would remain as approved. Avoid solving every complaint by relabelling the shoe or automatically moving all customers up one size.

5. Separate the approved size range from order quantities

A size chart does not confirm that every listed size is available for the selected order. Ask for the current range for the exact style and buying route, then prepare quantities within that confirmed range. Keep fit approval, stock confirmation and the commercial quotation as separate decisions. Approval of one sample does not reserve inventory or confirm every size in a production run.

Build your colour-by-size quantity matrix only after those limits are clear. Use your own customer evidence to choose the distribution; a supplier’s catalogue sequence is not a recommended sales ratio. If a requested size has not been confirmed, mark it as a question in the enquiry. Do not silently substitute another size or describe an unavailable size as made to order.

6. Keep a size approval record with the order

A compact record helps the buyer, supplier and listing team work from the same reference. The fields below are a preparation checklist, not a test certificate or a guarantee of fit. Keep revisions dated and make the person responsible for each pending confirmation clear.

7. Check labels before release and keep changes traceable

Before shipment, include size identification in the agreed inspection scope. Compare the ordered size mix with the pair markings, box labels and packing information. Check the relationship between these records rather than treating a printed size as proof of fit. Decide in advance how a mismatch will be reported and resolved; do not let an unclear label become a last-minute assumption.

Give your online listing team the approved chart and its scope, including any style-specific notes. Archive superseded versions so they are not reused for a repeat purchase. When a later order changes the construction or sizing reference, reopen the relevant approval points. This creates a clear trail from the sample decision to the information a customer sees.

Buyer questions

Is foot length the same as insole length?

No. One describes the foot and the other a shoe component. Ask which dimension the supplier’s chart uses and how it was measured. Do not insert an insole measurement into a column labelled foot length.

Can I use one high heel size chart for all styles?

Only after confirming its scope with the supplier and reviewing the relevant products. Keep exceptions visible. Similar photographs or identical size labels alone do not establish that two styles share the same fit.

Does approving one sample approve the entire size run?

It approves only the scope you have explicitly agreed. Record which size and version were reviewed, then agree any further checks needed for other sizes. Keep that decision separate from the final order quantity and availability confirmation.
