Clarks to Mizuno shoe size
The short answer
Clarks 5½ is Mizuno 5.5 by the two brands' own charts. 11 of 14 Clarks sizes land on a different label at Mizuno.
Both brands publish the foot length each size is built for, so every row matches a foot, not a label.
On 3 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
