A modular skating assembly for switching between types of skating styles includes a boot that is configured to couple to a foot of a user. A first coupler is coupled to a sole of the boot. Each of a plurality of second couplers is complementary to the first coupler. Each of a plurality of skate modules is coupled to a respective second coupler. The respective second coupler is positioned to couple to the first coupler to selectively couple the skate module to the boot. The improvement is the plurality of skate modules being selectively couplable to the boot, such that a pair of the boots is selectively configurable to enable a particular style of skating, such as in-line skating and roller skating.

The present disclosure relates to a shoe fastening system. The shoe fastening system includes a shoe part, a rail, and an insertable intermediate adapter for compensating a distance between the rail and the shoe part. The shoe part can have a flat underside. The rail can have a surface in the heel area which is raised relative to a ball area. The shoe part can have at least one displaceable mounting plate for screwing in a fastening screw for the intermediate adapter. The intermediate adapter has three through-openings for inserting a fastening screw. The first through-opening is arranged in the center of the intermediate adapter, the second through-opening is arranged on one side of the intermediate adapter and the third through-opening is arranged on the other side of the intermediate adapter.

A roller skate is provided, wherein the roller skate includes: a boot including a body portion and a sole, the sole having a longitudinal direction and including two receptacles arranged in interval in the longitudinal direction, each receptacle including a wall and at least one slot open on the sole toward the longitudinal direction, the wall defining at least one opening of the at least one slot; a roller assembly including a frame and rollers disposed on the frame, the frame including two insertion portions arranged in interval in the longitudinal direction, the two insertion portions being respectively insertable in and detachable from the two receptacles in the longitudinal direction, each insertion portion being blocked by the wall of one of the two receptacles in a blocking direction away from the sole; and a plurality of fasteners securing the frame to the sole.

A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.
