Women's 5 and men's 4 share this 220 mm foot, the one-number offset that runs through every unisex conversion and explains why men's and women's charts never line up.
CM to EU conversion
Converting centimetres to women's EU adds 13 to 15, the increment rising because EU numbers do not match millimetres one to one. So 23 cm reads EU 36 and 27 cm reads EU 42, and a half centimetre of growth moves EU by a full point in some places and only a half in others. Since a European last runs longer than the foot, two shoes both marked at your centimetre length can still fit apart, so read the EU result as an opening bid.
At this size, CM to EU
One size up from 22 cm, EU moves 0.5 to EU 35.5 while the metric length rises 0.5 to 22.5 cm. Both 22 cm and EU 35 are whole numbers here, so nothing rounds. For 22 cm, the EU column here runs EU 34.5, EU 35, EU 35.5, stepping a half size at a time.
This women's page reads 22 cm against
one gender grid, because men and women share a foot length but not a size
number: the same 22 cm in men's shoes is
EU 35 . Most charts pick a
gender without saying so, which is why a bare size search returns answers that
disagree by a full number.
Foot length vs shoe length
A CM shoe size is your measured foot length, not the space inside the shoe.
Brands add 0.5 to 1.0 cm of toe room so your toes clear the front. Japanese cm
labels already include about 1 cm of it, so a JP 24.0 measures near 25 cm
inside; an EU number instead describes the last. That built-in gap is why
conversion tables disagree.

Frequently Asked Questions Does 22 cm round up or down in EU? EU 35, US 5 and UK 3 land whole here, so this exact length rarely faces a rounding choice; between sizes, the larger laces down more kindly than the smaller pinches.
