Convert USA to UK Shoe Sizes
To convert USA sizing to UK sizing in shoes
As a rule subtract 1 from mens USA size & 3 from ladies USA size.
If you are normally a half size the conversion is a bit more complicated.
NOT WIDE WIDTH - If you sometimes have to buy a 1/2 size larger for a comfortable fit subtract 1 from the mens USA size & 3 from ladies USA. If you sometimes have to buy a 1/2 size smaller for comfort subtract 1 1/2 for mens USA & 2 1/2 for ladies USA.
WIDE WIDTH - Just subtract 1 from the mens USA size & 3 from the ladies USA size.
Just to make it a bit more complicated, sorry about that, UK sizes many times use the same shoe size with a different thickness insole. So if you find your new show slightly to large or small try changing the insole.
