Beyond the number
How to get a better fit
Measure both feet
Stand with your weight evenly distributed and measure from the heel to the longest toe.
Leave room at the toe
A comfortable shoe usually leaves about a thumb's width between your longest toe and the shoe's end.
Match the shoe to the use
Running, walking, and long work shifts place different demands on cushioning, support, and toe room.
Check width and brand notes
A correct length can still feel wrong if the width or shape does not suit your foot.
