How much room should be at the end of a shoe?
Check the space at the end of the shoe. Stand up and make sure there is 3/8" or 1/2" (about the width of your finger) between your longest toe (usually the second toe) and the end of the shoe. Always stand and walk around in the shoes to see if they are comfortable, fit well, and don't chafe or rub anywhere.
