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

If the size isn’t right? Don’t worry, our US returns are free of charge. 

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

The following list below will help you to identify your correct size. Please note that this list is a general comparison of sizing across brands and may vary based on person.

Crockett & Jones 325 last: Take the same US size equivalent

Last Details 

 

Both the Wayne and Alder lasts have a standard D width and a regular instep, but they differ in their toe box and overall width. The Alder last, used for our jumper boots, has a slimmer profile and overall width. The Wayne last, featured in our service boots, has a more voluminous toe box and a rounder appearance.
