2. Measure Your Feet Properly
A proper fit starts with knowing your true foot size, including length and width. Visit a specialist running store or ASICS store for a fitting, or measure at home using a printable shoe sizing guide.
Look out for terms like:
- D width: Standard for women
- 2E width: Standard for men; wide for women
- 4E width: Extra wide, commonly used by those with significantly wide feet or certain foot conditions
| ASICS Shoe Widths | Women | Men |

| Wide | D | 2E |
| Extra Wide | 2E | 4E |
