Size guide
Find your fit
The right fit
starts with your feet.
Finding the right fit matters — especially if you have wide feet, bunions or a high instep. Measure your foot, compare it with the insole length below, and you'll know your size before you order.
How to measure
Measure your foot in three simple steps
For the most accurate fit, measure both feet and use the measurement of your longer foot.
01
Stand on a sheet of paper
Place your foot against a wall with your heel touching the wall. Measure in the evening, when your feet are at their largest.
02
Mark your longest toe
Mark the end of your longest toe and measure from the wall to the mark in cm or inches.
03
Compare your measurement
Add ¼–½ inch (0.5–1 cm) for comfortable room, then compare with the insole length below.
Women's sizing
Find your size
Our styles come in US 4 to US 19. Compare your foot length with the insole length below.
Not every style is available in every size – the sizes you can choose on each product page are the sizes in stock for that style. Sizes can vary slightly between styles; if a product photo shows its own size chart, use that one.
Slippers & home shoes
Sizes in ranges
Some slippers and home shoes come in size ranges, such as US 6–7 or EU 36–36.5. Choose the range that includes your usual size. If you're between sizes, choose the larger range. One-size styles are designed to fit most adult women's feet.
Fit tips
A few things to keep in mind
Between sizes?
Choose the larger size, especially for boots and lined styles.
Wide feet or bunions?
Choose your usual size in our Wide Fit or Bunion-Friendly styles. There is usually no need to size up.
Wearing thick socks?
Allow an extra ¼ inch (0.5 cm) if you're wearing thick socks or your own insoles.
