For this style

Designed with a close fit.
we recommend one SR size up.

Simple Rainbow uses an international foot-length sizing system. Our sizing is based on foot length rather than brand-specific sizing.

we recommend measuring your foot length and selecting your size according to our size chart.

【how to measure your feet】

1. Please measure your feet while standing, not sitting. Your feet naturally spread a little when you're standing, so the measurement will be more accurate.

2. Make sure the ruler is perfectly perpendicular to the paper. If it’s at an angle, the measurement can easily be inaccurate.

3. The foot length should be measured as the straight-line distance between the line at your longest toe and the line at your heel.

If your measurement falls between two sizes, we generally recommend choosing the larger size. Only customers with particularly narrow and slim feet may prefer the smaller size.

If your left and right feet differ in length, please use the measurement of your larger foot when selecting your size.
