FAQ About Sizing

Frequently Asked Questions

Should I measure myself or use brand size charts?

Measure yourself first, then use brand charts as a secondary reference. Your measurements are more reliable.

How do I handle one-size-fits-all items?

Track the actual measurements and your fit experience. "One size" varies dramatically between sellers.

What is the most important measurement for shoes?

Insole length in centimeters. This is the most universal and comparable measurement.

Can I predict fit for new sellers?

Use your historical data from similar items. Compare measurements rather than relying on size labels.
