What Is Inventory Shrinkage from Overproduction and Scrapping Slow-Moving Size SKUs?

Footwear brands often overproduce tail sizes (extreme small/large) based on historical curves that don't reflect current demand. Unfair Gaps analysis shows brands without dynamic size curve analytics write off 8–15% of tail-size inventory annually.

How This Problem Forms

Financial Impact

Who Is Affected

Inventory managers and CFOs at brands with >100 SKUs and wide size ranges face the highest write-off risk. Unfair Gaps research shows kids' and performance footwear have the most volatile size curves.

Frequently Asked Questions

What causes overproduction of slow-moving footwear sizes?▼

Static historical size curves that don't reflect current demand, combined with no in-season slow-mover detection, cause brands to overproduce tail sizes by 20–40%.

How can footwear brands reduce size inventory write-offs?▼

Dynamic size curve analytics with early markdown triggers at 60% of season can reduce write-offs by 50–70% — Unfair Gaps analysis shows best-practice brands achieve <2% size write-off rates.
