01Measure your foot

  • Stand on a sheet of paper against a wall, with your heel touching the wall.
  • Mark the tip of your longest toe and measure from the wall to the mark, in centimetres.
  • Measure both feet, preferably in the evening when they are largest, and use the longer measurement.
  • Find the closest length in the chart below. If you fall between sizes, read the advice by style.

Women: choose the UK size shown for your foot length; US women’s sizes are approximately US men’s + 1.5.

03Fit by style

  • Sneakers & runners — true to size. Between sizes, choose the larger.
  • Loafers — a close fit when new; the leather relaxes with wear. Between sizes, choose the smaller.
  • Boots — true to size with room for a medium sock. Between sizes, choose the larger.
  • Slides — your toes should sit just within the footbed; between sizes, choose the larger.
