How to Reduce Footwear Returns (Width, Not Length)
Footwear has one of the highest return rates in ecommerce, and the reason is usually misdiagnosed. Customers report "too small" when the shoe was the right length and the wrong width.
Quick answers
- Why do shoes get returned?
- Width, far more often than length
- What should I publish?
- Foot length in mm AND width fitting
- Why mm?
- It's the only unambiguous, system-free measure
- Do shoes vary by brand?
- Yes — say plainly how yours run
Footwear: Cause and Fix
| Cause | Fix |
|---|---|
| Width, not length | Publish width fittings |
| Brand size variation | State how the brand runs |
| Foot length unknown | Give a printable measuring guide |
| Sizing system confusion | Show US/UK/EU + mm |
| Sock thickness ignored | Mention intended sock |
Notes
"Too small" usually means "too narrow." The customer knows their length. When a shoe pinches, they conclude it's too small and return it for a bigger size — which is then too long. Publishing a width fitting lets them identify the real problem and order correctly.
Millimetres are the only honest measure. US, UK, and EU shoe scales don't align cleanly, especially in half sizes. Foot length in millimetres is unambiguous. Publish it alongside the size labels, and give shoppers a printable guide to measure their foot at home.
Say how your shoes run. Footwear sizing varies more by brand than almost any other category. "Runs a half size small — we recommend sizing up" is one sentence that prevents a huge share of returns. Shoppers actively look for it.
Don't forget socks. A running shoe fitted with thin socks and worn with thick ones is a return. If the shoe is intended for a particular sock weight, say so — it sounds trivial and it isn't.
FAQs
Why do customers return shoes that are the right size?
Because the problem is usually width, not length. The shoe pinches, the customer concludes it's too small, and they exchange for a longer size that then doesn't fit either. Publishing width fittings lets them identify the real issue.
What should a shoe size chart include?
Foot length in millimetres (the only unambiguous measure, since US/UK/EU scales don't align cleanly), width fittings, the equivalent size labels in each system, and a plain statement of how your shoes run versus standard.
How do I help customers measure their feet?
Give a printable measuring guide — stand on paper, mark heel and longest toe, measure the distance in millimetres — and publish your shoes' internal length in mm so they can compare directly rather than trusting a size label.
