The best way to measure to your current Archies Jandals is to do the following:

1. Use a ruler to measure on the underside / grip side of the jandal, NOT the top of the jandal.

2. Lay the ruler along the length of jandal using the marking points provided, ensuring that the ruler is firmly pressed against the jandal and the jandal is fully stretched out.

3. Take the measurement from the furthest point of the jandal that you can see (this point is on the top of the jandal as the underside / grip side is slightly angled in). Please be as accurate as possible and measure to the nearest mm.
