The verdict

True to size, with room for your toes.

Yes: most Altra running shoes are true to size, with a roomy toe box. Wide fits are available.

True to size, with a foot-shaped toe box that lets your toes spread. If your feet are narrow, they can feel loose up front.

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 Altra 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 Altra make wide-fit running shoes?

Yes. The Torin 9 comes in a wide fit.

Is Altra 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: Altra is roomier than most Nike running shoes.
