Caswell uses the US sizing system for all boots and loafers. All lasts run true to brannock size and feature a regular instep.

If the size isn’t right? Don’t worry, we offer free exchanges for all RTW items.  

If you have other dress shoes, like Carmina, Meermin, or Crockett & Jones, simply choose the same US size equivalent in our boots or look at our brand comparison list below for further details. For trainers and sneakers from brands such as Nike, we recommend that you choose one half size smaller.

For loafers, we recommend selecting one full size smaller than your standard brannock size. For example, if your standard brannock size is a 10D, select 9D for your loafer size. 

If you have any questions or want to confirm your sizing, please reach out to us at contact@caswellboots.com and we'll be happy to help.
