Retail footwear inventory

Wholesale shoe size run planning

A size run is an inventory decision, not a generic ratio copied from another market. The right opening curve depends on product sizing, fit, target customer, selling channel, available quantity, carton constraints and the retailer's ability to learn and reorder.

Direct answer

The short version

Choose one primary size system and record the supplier's size-to-foot-length or last information for the exact model. Approve fit on representative samples, then combine target-customer evidence, comparable store sales, channel returns and supplier minimums into a size-by-size opening quantity. Keep conversions as guidance rather than promises of identical fit. Reserve depth for core sizes, retain enough edge sizes to test real demand, label every variant consistently and set a dated review that uses sell-through, stockouts, returns and exchange requests before reordering.

Build an opening size run buyers can learn from

01

Identify the exact footwear model

Record style, construction, target wearer, width or fit designation, color and supplier model. Do not assume two shoes from one supplier fit the same because they carry the same printed size. Material, last, toe shape and construction can change perceived fit.

02

Choose one primary size system

State whether ordering uses EU, UK, US, Mondopoint or another supplier system and keep it consistent across purchase order, carton, barcode and listing. Use foot length as a documented reference where available. Do not mix men's, women's and children's conversions silently.

03

Approve fit before allocating depth

Evaluate representative sizes with the footwear sample checklist. Record internal length method, width, entry, heel hold, toe room, fastening range and tester foot measurements. Fit comments such as runs small need a stated evidence set and model scope.

04

Build the demand evidence

Use comparable-category sales, customer profiles, search or wish-list signals, past stockouts, returns and exchange requests from the same channel. Separate demand from availability: a size with low sales may simply have been out of stock.

05

Allocate the test curve

Give core sizes enough units to stay available while retaining measured edge-size coverage. Show percentage and unit count for every size. Check supplier MOQ, prepack ratios and case quantities, but do not let a convenient carton create an unexamined retail curve.

06

Control size labels and variants

Assign each style-color-size combination its own SKU and, when required, GTIN. Reconcile shoe marking, box label, purchase order, packing list, warehouse location and ecommerce variant before shipment release.

07

Review size performance correctly

At a fixed date, compare sell-through, weeks available, stockouts, returns, exchanges and customer fit comments by size. Increase depth only when the signal is real. Keep obsolete conversions and curves versioned so the next order uses current model evidence.

Questions buyers often ask

What is a shoe size run

It is the quantity allocated to each size for one style and color. A useful run reflects the exact model, target shoppers, channel evidence and replenishment plan.

Can retailers use one universal footwear size curve

No universal curve fits every customer, model or channel. Start with evidence, test broadly enough to learn and revise from availability-adjusted sales and returns.

Are EU, UK and US shoe sizes directly equivalent

Conversion guidance exists, but systems and product fit are not identical promises. State the primary system, foot-length basis and model-specific fit evidence.

Should low-selling edge sizes be removed immediately

Check whether they were available long enough and whether customers requested them. A controlled test prevents stockouts or missing inventory from being mistaken for no demand.

Keep the request specific

A conversion table does not guarantee identical fit

ISO 19407 provides guidance across major sizing systems based on foot length, but product construction and interpretation still matter. Publish the model's reviewed size information and fit notes; do not promise that one printed size fits every wearer or equals every other system.
