US Trends

what is size 43 in us

Size 43 in EU is usually about a US men’s 9.5–10, and a US women’s 11–11.5, depending on the brand and the specific conversion chart you use.

Quick Scoop: Size 43 → US

For men’s shoes :

  • Most generic charts place EU 43 around:
    • US 9.5–10 (men).
  • Some brand examples:
    • Nike/Adidas often show US 9.5 or 10 printed as EU 43 (sometimes 43 or 43⅓).

For women’s shoes :

  • Many charts map EU 43 to:
    • US 11–11.5 (women).

Why it’s a range (not one exact size)

Shoe conversion isn’t perfectly standardized:

  • Different brands use slightly different charts, so the same EU 43 can be labeled US 9.5 in one brand and US 10 in another.
  • Some retailers even show 43 as 9.5–10 in a single line (one number covering the range).

Think of it like T‑shirts: you might wear “M” in one brand and “L” in another—same idea with EU 43 in shoes.

Quick check list to get it right

  1. Look inside a pair you already own.
    • Check the label: if your comfortable US 9.5 shows “EU 43”, that brand treats 43 as 9.5.
  1. Check the brand’s own size chart.
    • Most official websites (Nike, Adidas, etc.) host a conversion table that shows exactly what they call EU 43 in US sizing.
  1. If shopping online and unsure:
    • If your foot length in centimeters is around 27 cm, you’re typically in the EU 43 / US men’s 9.5–10 zone.

In forum discussions, many sneaker buyers end up choosing US 9.5 when they see EU 43, especially for brands like Nike, but others go for US 10 depending on how they like their fit.
