🎯 Pro fit tips (from footwear specialists)

  • ✔️ Measure both feet — always use the longer foot length.
  • ✔️ Take measurements standing up, with weight evenly distributed.
  • ✔️ For running or active shoes, add 0.5–1 cm to your raw foot length to allow toe clearance.
  • ✔️ US sizes often vary between brands — compare your EU or cm size as the most universal reference.
  • ✔️ Half sizes matter: if your length lies between two sizes, choose the larger half size for comfort.
  • ✔️ Evening measurements are best (feet naturally expand after daily activity).

❓ Frequently Asked Questions

What’s the difference between US Men and US Women sizes?

US Women’s size is typically 1.5 sizes larger than US Men’s (e.g., Men’s 8 = Women’s 9.5). Our calculator shows both conversions regardless of gender selection, so you never get confused.

Why does Korea show “mm” and Japan shows “cm”?

Korean shoe sizing directly uses millimeters of foot length (eg 260mm = 26.0cm), while JP size uses the same number in cm. This follows local industry standards for precise manufacturing.

How accurate is the conversion model?

We follow the ISO/TC 137 standards adapted with EU Paris point (1 Paris point = 2/3 cm). Our formulas align with major footwear manufacturers worldwide. Always try shoes when possible.
