  • Patent number: 9648921
    Abstract: A shoe having a hinge member incorporated between a footbed toe plate and footbed arch plate allowing the shoe to be configured as a flat or heeled shoe. The footbed toe plate and footbed arch plate are rotatably joined via one or more hinge pins inserted through interlaced teeth of each plate. A spring-biased hinge lock extending between the plates is controlled by a spring-biased pin having a notch for selectively receiving the hinge lock such that the hinge lock disengages the footbed arch plate allowing the footbed arch plate to rotate relative to the footbed toe plate. The heel block includes a spring-biased heel lock extending into a removable heel and is controlled by a spring-biased pin having a notch for selectively receiving the hinge lock such that the hinge lock disengages the heel allowing the heel to be removed from the heel block.

The footbed toe plate and footbed arch plate are rotatably joined via one or more hinge pins inserted through interlaced teeth of each plate. A spring-biased hinge lock extending between the two plates is controlled by a spring-biased pin in positioned with a notch selectively receiving the hinge lock such that the hinge lock disengages said footbed arch plate allowing said footbed arch plate to rotate relative to said footbed toe plate. The heel block includes a spring-biased heel lock extending into a removable heel and is controlled by a spring-biased pin positioned with a notch selectively receiving the hinge lock such that the hinge lock disengages said heel allowing said heel to be freely removed from said heel block.
