A men's UK shoe size converts to EU through the same foot-length-anchored chart used for US conversions. As a reference point, a UK 8 is an EU 42.5.
UK men's shoe sizes run one whole size below the equivalent US men's number for the same foot (a UK 8 is a US 9), which carries through to the EU conversion: a UK 6 is an EU 40, a UK 8 is an EU 42.5, a UK 11 is an EU 46.
As with the US chart, the EU number is anchored to centimeter foot length rather than a fixed step from UK, so brands vary slightly at the half sizes — the measure-your-foot tool on the main shoe converter is the more reliable check if you're near a size boundary.

A men's UK 8 is an EU 42.5, the same physical size as a US men's 9.
One whole size — a UK 8 is a US men’s 9, a UK 10 is a US men’s 11, and so on.
No — always convert with the men's chart for a men's UK size and the women's chart for a women's UK size; the same UK number means a different EU size in each.
