Common questions
Why use millimeters for Korean sizes?
Many Korean shoe listings use millimeter sizing directly, so mm is the clearest starting point.
Is conversion exact across brands?
No. Brand last shape and fit vary, so the tool is an approximation.
Should I size up for wide feet?
Often yes, especially when you are between sizes.
