Most would say that J.FitzPatrick Shoes run 'true to size.' Of course this depends on the last. For the most part we have a more generous instep than not (handgrade line), if you could create one rule across all of our shoes in that line. Forefoot width (narrow vs wide) will vary across the lasts (also handgrade line).

All of our shoes are made on the UK sizing system but translated to US sizes on the website. Our sizes are based on the UK standard, where ‘E’ is the “medium” width being equivalent to a US ‘D’ width. If you have always been size US10D, then this is what you should expect to be in 90% of our footwear as well. The exceptions will be the chisel lasts in the Handgrade line. Inside the shoes, you will see the UK size, but on the box, you will see UK, US and EU sizing listed.

Please note that our shoes are sized based on the idea of one size difference between UK and US sizing. For example, if you are UK9, you will need our US10.

Four of the eight lasts for our J.FitzPatrick Handgrade Line were created with the same heel to ball of foot ratio, only changing the shape of the toe (i.e. forefoot), thus ensuring a standard arch fit across all models. These are the TMG, JKF, MGF and LPB. This does not mean they all fit the same though. For the NGT, SEA and SES lasts, we tightened the waist for a more snug mid-foot fit. On the NJF last, we gave a more generous mid-foot as it was intended for fuller style boots.

Please read our Last Guide for further descriptions on each last.

While fit will be similar one must take into account that loafers will fit differently to oxfords and oxfords will fit differently to derbys and all of them differnt to monkstraps and boots. So, while you may feel good in the fit of an oxford, the same size in a derby might feel loose due to the extra room in the instep created from the open lacing. And while you fit good in a US10 in a monkstrap, on a boot you might need a US10.5 to not feel constricted. This has nothing to do with size however, but more so the nature of the different models in footwear, their patterns and where certain seams fall. Understanding this will help you choose your size more accurately.

Note that our loafers are purposely cut small to account for the style's lack of laces or buckles which could be used to re-tighten shoes upon wearing. We cut our loafers to fit initially tight and typically recommend that you take the same size as your oxfords. However, if you like to wear your oxfords very snug, then we recommend size up on your loafers.
