It’s important to firstly measure your inside leg. If your leg fits in two size brackets, choose the size that also matches your height.

How to measure

Inside leg:
  • Stand with your back to a wall in socks. Ensure your feet are flat on the floor.
  • Place a book between your legs.
  • Slide the book up the wall until it contacts the crotch firmly.
  • Ask someone to mark the wall at that point.
  • Measure from the mark straight down to the floor.
  • Place the book flat on your head.
  • Mark where the bottom of the book touches the wall and measure straight down to the floor.
