Respectively subtract at least 1/2 to your men’s shoe size number to get your women’s size. It gets more complicated if you want to convert, for example, European men’s shoe sizes to UK or US women’s sizes. As always, this is not an exact science, and it may well be that the men to women conversion works very differently for your preferred brand. However, in some cases, your UK men’s size is the same as your women’s size.
What can be said is that men’s shoes are generally a bit wider than women’s. So, you may want to choose men’s shoes that’s a bit smaller than you’re typical size if you are a woman."
