Investing in a pair of premium, Goodyear-welted shoes is an unmatched experience in style and longevity. However, unlike mass-produced trainers, high-end shoemakers like Trickerβs, Berwick 1707, and Paraboot rely on traditional, distinct "lasts" (the wooden or plastic moulds used to shape the shoe).
Because different lasts alter the width, instep, and toe-box room entirely, a size 8 UK in one brand can feel completely different in another.
To take the guesswork out of ordering online, here is our definitive, three-step master guide to finding your perfect fit using our data-backed AFPOS Shoe Sizing Tables.
Step 1: Measure Your Foot in Centimetres (The Right Way)
Do not rely on your standard high-street shoe size. Instead, grab a sheet of blank A4 paper, a pencil, and a ruler:
- Trace your foot: Stand firmly on the paper and trace around your foot. Keep the pencil perfectly vertical to prevent adding or subtracting millimetres.
- Measure length: Measure the exact distance from the very back of your heel to the tip of your longest toe.
- Add your wiggle room: Round up your final measurement to the nearest 0.5cm. If you have slim or regular-width feet, add 1cm extra. If you have wider feet, add 1.5cm extra.
Step 2: Deciphering the Major Shoe Lasts
Once you have your adjusted centimetre measurement, you need to match it to the specific last of the shoe you want. Here is how our most popular brands compare:
Berwick 1707 Last Sizing
The 915 Last (Chiselled/Elegant)
Trickerβs Last Sizing
The 4444 Last (Country Shoes/Boots)
Step 3: Decoding Width Fittings (UK vs. US)
Letters denote shoe width, but British and American manufacturers use entirely different alphabets. Use this quick reference chart before placing your order:
| Fit Profile | UK Width Letter | US Width Letter |
|---|---|---|
| Slim / Narrow | E | C |
| Regular / Standard | F (or 5-6) | D |
| Wide | G (or 6-7) | E / EE |
| Extra Wide | H | EEEE |
Sizing FAQ: Fast Answers for Fine Footwear
What is the difference between UK and US shoe sizes?
As a general rule, a US size is one full size larger than a UK size (e.g., a UK 9 typically converts to a US 10). However, variations between manufacturers mean checking exact internal centimetre lengths is always safest.
What should I do if I have a high instep or low-volume foot?
If you have a high instep (the top arch of your foot), Oxfords may pinch; consider opting for Derby shoes or adjusting your size up by a half-size. For low-volume feet, a premium leather insole can safely bridge the gap.
