Size Guide
SHOES
We are currently using Asian/European sizing for our footwear. To find your best fit, follow these steps:
-
Measure your foot
Place the back of your foot against a wall on level ground. Then measure the distance from point A to B.
The distance between A and B is the length of your feet. -
Select your size
Refer to the size conversion chart below and select the size closest to the length of your feet.
| Size | ASIA / EU | US | UK / IN | JP / MX | KR / CN | Length of Foot (CM) |
|---|---|---|---|---|---|---|
| S | 34 | 4 | 1 | 22 | 220 | 21.7 |
| 35 | 5 | 2 | 22.5 | 225 | 22.3 | |
| M | 36 | 6 | 3 | 23 | 230 | 23 |
| 37 | 7 | 4 | 23.5 | 235 | 23.7 | |
| L | 38 | 8 | 5 | 24.5 | 245 | 24.3 |
| 39 | 9 | 6 | 25 | 250 | 25 | |
| XL | 40 | 10 | 7 | 25.5 | 255 | 25.7 |
| 41 | 11 | 8 | 26 | 260 | 26.3 | |
| 2XL | 42 | 12 | 9 | 27 | 270 | 26.9 |
| 43 | 13 | 10 | 27.5 | 275 | 27.5 |
- CHARLES & KEITH uses Asian/European size for its footwear collection.
- If both sides of your feet are different in length, we recommend you select a shoe size based on the longer side.
- The current recommended size chart does not include half size recommendations. We suggest you select the shoe size based on the length closest to your feet measurement.
- Please note, foot length is not equivalent to shoe length.
- Shoe comfort is dependent on a combination of factors such as size, design/cutting and heel height. For example, shoes that are of the same size, but are different in design/cutting, may not give you the same level of comfort.
- These are recommended guidelines to get you the best possible fit for CHARLES & KEITH footwear collections only.
