ABSTRACT:
A convertible sports device has a housing, and sport members movable between an extended and a retracted position relative to the housing. An arresting member is provided, which in a first position abuts against a first face of each of the sport members so as to arrest them in the extended position, and in a second position abuts against another face of the sport members so as to arrest the latter in the retracted position. The housing may be formed as a bottom portion of a shoe or may be attachable to the shoe. The arresting member may be actuated by an actuator which, in turn, may be actuated by a foot of a user so that the sport members may be retracted or extended without the need to use one's hands.
