  • Walking and in-line skate shoe
    Patent number: 6343800
    Abstract: A convertible shoe that can be used for walking or for in-line skating having an extendable and retractable wheel mechanism. The convertible shoe has cavities in the sole of the shoe capable of storing and enclosing the retracted wheel mechanism. The wheel mechanism allows the wheels to be held perpendicular to the walking surface of the sole when the wheel mechanism is extended, and parallel to the walking surface of the sole when the wheel mechanism is retracted. With the wheel mechanism extended, the convertible shoe can be used for in-line skating. With the wheel mechanism retracted and stored in the sole, the convertible shoe can be used for walking.
