Stand on a sheet of paper with your heel against a wall, wearing the socks you'd run in. Mark the paper just past your longest toe, then measure from the wall to the mark. Do both feet and use the longer one.

These sizes are a racing fit, with only a couple of millimetres of room at the toe. If you're between sizes or want more room, go up a size.
How wide does it fit?
VJ grades every shoe from 1 (narrow) to 5 (wide). A narrow fit keeps your foot still on fast, technical ground. A wide fit suits wider feet and long races, when feet tend to swell.
