A device for retaining the shape of a shoe includes a tapering base member having an arch cross section and a shoe expansion member defining a cavity removably receiving the base member therein. The base member has opposite side walls and an arcuated top wall defining a groove in which a stair-like configuration is formed, having a first number of steps. The side walls of the base member each form first serration. The shoe expansion member has a bottom in which the cavity is defined and a top side configured to closely fit into a shoe for retaining the shape of the shoe. The cavity is defined by opposite side walls and a top wall. The top wall of the cavity has a stair-like structure having a second number of steps. The side walls of the cavity form second serration. The stair-like structure of the cavity is at least partially engageable with and supported by the stair-like configuration of the top wall of the base member. The second serrations are engageable with the first serrations for securely fixing the shoe expansion member with respect to the base member. An additional shoe expansion member may be selectively included. The additional shoe expansion member may be of different sizes and shapes for replacing the original shoe expansion member to be fit for shoes of different sizes and shapes.
