Fit of Archies Thongs and Slides

Our thongs and slides should “fit like a glove” with very little space in front of the toes and behind the heels. 

For our thongs and slides, we suggest selecting your standard running shoe size. You can also measure your footlength and use the size chart below. 

    How to measure your footlength

    1. Place a piece of paper on a hard surface.
    2. Stand with the back edge of your heel lined up with the edge of the paper.
    3. Use a pen to place a mark behind your heel and at the top of your longest toe.
    4. Use a ruler to draw a straight line between the two. (It will be a diagonal line)
    5. Measure the length in cm and use our chart. For example, if your footlength is 24.8cm, the perfect range will be 24.3 - 25cm which is a US Men’s 7 / US Women’s 8 (UK 6 -6.5 or EU 39.5 - 40)

    Half sizes

    If your feet are a half-size, we recommend sizing up to the next size.

    • The size of our insoles is based on the size of the shoe and not your footlength.
    • If your shoe size is a half size, size down.
    • Choose the same US size as your shoes or remove the insole and measure it. Use the size chart below to find the appropriate size according to the length.
