Which size fits which foot

A UK size is a barleycorn measure: one size is a third of an inch, counted from the length of the last. The last is your foot plus about 1.5 cm of room, which is the same allowance the European number is built on – so both columns come from one measurement. Measure the foot, not the insole: stand on a sheet of paper, in the evening, wearing the sock you will run in.
