01Identify 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.
02Choose 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.
03Approve 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.
04Build 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.
05Allocate 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.
06Control 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.
07Review 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.
