Question: what is the difference between wide and regular shoes?
Answer: When measured at the ball-of-the-foot, the difference between shoe widths is approximately 1/4”. A wide width is 1/4” wider than a medium width and an extra wide width is 1/2” wider than a medium width. ... In general, the instep girth of the shoe increases 3/16” for every increase in width for the same length.
