Many people think that a shoe fits if there is a thumbs width of room in the toe, but that’s not necessarily true. The most important thing to look for is where the ball of your foot sits in the shoe. Regardless of the length, if the widest part of your foot fits into the widest part of the shoe, the shoe will likely fit well and be comfortable. In some shoes, that may leave you with a half inch or less between the end of your longest toe and the end of the shoe, in other styles it may be an inch or more. Don’t worry about that as much, as long as the ball of your foot is in the widest part of the shoe you’ve got the right size.
