EU to US Sock Size Conversion
| EU Shoe Range | US Shoe Range |

| 39-42 | M (7-9) |
| 43-46 | L (10-12) |
Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A EU 39-42 sock range matches a US 7-9 shoe range on the standard chart — the number to use when a European sock brand's packaging prints only the EU figure.
If your foot size sits right at the edge of one of these ranges, checking the brand's actual stretch tolerance (some socks are cut tighter through the arch than others) matters more than picking the technically correct range.
Frequently asked questions
What if my shoe size is right on the boundary between two sock ranges?
Either range usually works given how much knit sock fabric stretches, but a tighter-knit brand may fit better sized up; check the brand's own note on stretch if your size is right on the edge.
