The first collection slip ons in canvas upper (Freakshow, Egypt, Tacos and Nerdy) had a wide fitting upper but it is not as deep as the Chocs. Most people found that if they wore a firm/snug fit in the chocs, their same size in the slip ons were too tight. Freakshow and Nerdy have now been restocked in the new fit profile explained below.
All the subsequent releases (Garden, Ombre, Dino, Fallen Angels, Colorama, etc), have an improved fit profileand slightly more depth, so most people (around 70%) are finding they can now fit their usual size in the slip ons, especially if their Mary Jane style Chocolaticas are a loose fit. Those with snug/firm fitting MJs still might want to size up in the slip ons, especially if they have a wide foot. Narrow feet often find the slip ons hard to keep on their feet.
