Converse shoes claim to run a half size large, meaning that a size 9 will fit like a size 9-1/2. My experience, however, is that Converse All-Stars (or Chuck Taylor s) tend to run a full size larger than the average sneaker.
Fun fact: Converse once ran a monopoly on sneakers worn by the NBA. The shoes were designed to be worn with an extra pair of socks, so they run a half-size (to a full size) larger.
