Running Shoe Size Guide
Running shoes need enough space for toe movement and foot swelling, but too much space can make the shoe unstable.
How running shoes should fit
A running shoe should feel secure through the midfoot and heel, with room at the toes. Many runners prefer a little more length than in casual shoes.
- Check toe room while standing.
- Try running socks, not thin dress socks.
- Watch for pressure on the little toe or toenails.
Should you size up for running shoes?
Some runners go half a size up, especially for longer distances. Do not size up if the heel lifts or the midfoot feels sloppy.
Common questions
Should running shoes be bigger than normal shoes?
They can be slightly bigger, but only enough to allow toe movement and swelling without heel slip.
Does running shoe width matter?
Yes. If the length is right but the sides feel tight, look for wide options rather than simply sizing up.
