A base structure for a roller skate includes a base having at least two compartments, a bottom plate secured to the base, and a number of wheel assemblies each of which is mounted in an associated compartment. The bottom plate includes a number of blocks formed on the underside thereof, each block being received in an associated compartment. Each wheel assembly includes a pivotal seat having a first end secured to the underside of the bottom plate, a wheel seat having a first end pivotally connected to a second end of the pivotal seat, and a wheel rotatably mounted to a second end of the wheel seat. Each wheel seat may be pivoted to a storage position in the associated compartment when not in use. When skating is required, each wheel seat is pivoted to an operative position, in which each wheel seat bears against an underside of an associated block while the wheel rotatably attached to each wheel seat extends beyond the base for skating.
