Barefoot Shoe Fit & Size Comparison Worksheet

MEASURE · RECORD · COMPARE

Your measurements. Your chosen room.

Compare up to three manufacturer-listed internal dimensions against both feet and your own allowances. This worksheet does not convert shoe sizes or recommend a brand or size.

Check the chart first. A foot-length chart is not an internal-shoe chart. Last and insole measurements may differ too. Confirm the manufacturer’s method so you do not add room twice.

Use digits and one decimal dot or comma, without grouping. Calculations use exact whole micrometers. Unit changes retain exact values; converted fields display rounded values until edited. Invalid entries stay invalid after a unit change. Clear and re-enter them in the current unit.

1 / Measure both feet

Record heel to longest toe and forefoot width while standing. Note intended socks and measurement conditions; time and activity can change measurements.

Plan your next fit check

Use these guides alongside the measurement and chart-comparison guide above. Manufacturer lasts and models vary; dimensions do not capture heel hold, upper volume, or personal comfort. Check model-specific guidance and return terms, and try on when possible.
