Talk:Shoe size

US sizes vs. UK

While describing the difference between US and UK sizes, it says the "zero point" for US men's sizes is related to the largest US children's size, AND it says that the first US men's size is "size 1".

This is unclear. Is "size 1" at the zero point? Or does the zero point mean "imaginary size 0, smaller than size 1"?

Maybe "zero point" is a term that works better when confined to the UK, where a size 0 shoe exists. But we can't start calling it a "one point" for the US instead, that would be extremely confusing. I don't know. TooManyFingers (talk) 15:25, 20 April 2025 (UTC)

The zero point is the point relative to which the sizes are named, so it still makes sense to speak of one for the US system, even if there are no size 0 shoes. Eishiya (talk) 20:17, 9 June 2026 (UTC)

"Customary" US system is a false term

In the section on US sizes, we describe a system that we call customary, BUT in the next sentence we explain that what we have just described is not customary. This is insane. TooManyFingers (talk) 05:49, 28 April 2025 (UTC)

Foot size/length. Shoe size

Unclear comparison:

1) the calculation for a child's foot size in the UK is:

child foot size = 3 × last length (in) − 12

equivalent to: child shoe size ≈ 3 × foot length (in) − 10.

And similarly for adults. — Preceding unsigned comment added by ~2026-31698-53 (talk) 07:56, 28 May 2026 (UTC)

2)shoe size (Paris points) = 3⁄2 × last length (cm) equivalent to: shoe size (Paris points) ≈ (3⁄2 × foot length (cm)) + 2

As can be seen the latter gives two calculations for shoe size, one derived from foot length and the other from last length, but the former has foot length, foot size, last length and shoe size. I think "foot size" should in fact say "shoe size". ~2026-31698-53 (talk) 07:48, 28 May 2026 (UTC)

Conversion

The conversion formula given says that 10 UK = 43.91 EU. I recently bought a pair of size 44 trainers which were marked 44 / 9.5 and I have another pair marked 44.5/10.

I know it's an inexact science, but these two examples suggest the formula is wrong. ~2026-31698-53 (talk) 15:36, 1 June 2026 (UTC)

Italian to US shoe size conversion data

I have a conflict of interest because I am associated with the website publishing this source, so I am suggesting it here rather than adding it directly to the article.

Size Chart Guru published a data study comparing official size charts from 26 Italian footwear brands, including men's and women's US-to-Italian/European size conversions and published foot-length measurements. The analysis found that conversions vary between brands even when the same US or European size labels are used.

The study may be relevant to the sections discussing differences between shoe-sizing systems and manufacturer variation.

I welcome independent editors deciding whether the source meets Wikipedia's sourcing requirements and whether any of the findings are appropriate to include. CuriousSole (talk) 11:52, 25 September 2026 (UTC)

Seems promotional, so no thanks. You added a different link to your website directly to the article instead, two days later. I've removed it. --Belbury (talk) 12:39, 2 October 2026 (UTC)
