The tables below give the measurements for your size and width. These measurements are in mm. Take your width and length measurements and find the corresponding size.
For example, if you're a size 8 and the width of your foot is less than 93mm you need a narrow B fitting. If it is more than 104mm you will need a 2E wide fitting, but if it's more than 114mm you need a 4E extra wide width fitting.
- B fitting - for narrow feet
- D fitting - for medium feet
- 2E fitting - for wide feet
- 4E fitting - for extra-wide feet
