- 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.
