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 Karhu 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 Karhu make wide-fit running shoes?
Yes. The Ikoni 3.5 comes in a wide fit.
Is Karhu 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: Karhu is a little roomier than most Nike running shoes.
