The verdict

True to size, right across the range.

Yes: most ASICS running shoes are true to size, with a standard width. Wide fits are available (2E for men, D for women).

True to size across the cushioned and stability range. The Metaspeed racers are snugger, as race shoes usually are.

Between sizes?

Running shoes should leave about a thumb's width between your longest toe and the end of the shoe. Your feet swell on longer runs, so a shoe that feels just right in the shop can feel tight at mile ten. If you're between sizes, go up half a size for long runs and marathons; for short, fast race shoes, a closer fit is fine.

If your feet are wide, a wide version beats going up a size: a longer shoe adds length where you don't need it, and your foot can slide around.

Frequently asked questions

Should I size up in ASICS running shoes?

Not usually: go with your normal size. If you're between sizes, or run long distances where your feet swell, half a size up gives your toes more room.

Do ASICS make wide-fit running shoes?

Yes. The Gel-Cumulus 28, Gel-Kayano 33, Gel-Nimbus 28, GT-2000 15 and Novablast 6 come in a wide fit (2E for men, D for women).

Is ASICS sizing the same as Nike's?

For length, mostly yes: your usual trainer size should work in both. Nike's race shoes are the exception, as they run small. Width is where they differ: ASICS is a little roomier than most Nike running shoes.
