Frequently Asked Questions
Do ASICS shoes run true to size?
Many runners find ASICS close to true to size for length, though some prefer a half size up for toe room on long runs. Compare your foot length in cm to the chart for the most reliable match.
What do ASICS width or last options mean?
ASICS often labels lasts as normal or wide. For US letters, men's normal is typically D and wide is often EE / 2E; women's normal is typically B and wide is often D. Extra-wide options appear on select models.
How do ASICS kids sizes work?
ASICS kids sizes use US youth/toddler-style labels with UK, EU, and cm. Measure foot length in cm and use the kids table below rather than guessing from adult sizes.
