Women's Sandals Size Guide | Low Thickness + Low Arch Support (KS-1)

Our different types of midsole (i.e. as determined by the thickness and level of arch support) may have slight variations in length and width. Please always check the midsole details (and ID) above to make sure that you're referring to the correct size guide.

Measuring Tips to Ensure the Best Fit

To determine your shoe size, there are 2 things you need to measure: your foot length and width.

Once you have your foot measurement (in centimetre and millimetre), you can then find your size by referring to the size table below.

**Please do not round up or down your size measurement but be as accurate as possible.**

This design has low arch support and is only recommended in the following cases:

  • You have flat feet and this will be your first time wearing comfort shoes with arch support (in which case we would recommend gradual adjustment, i.e. getting used to the low arch support first before moving on to normal arch support).
  • You have normal feet but you prioritise the design over the comfort for your feet that the medium arch support provides.

If this is your first time purchasing our products, please read our explanations on different levels of arch support before making your purchase. Inappropriate selection of arch support could result in discomfort for your feet.
