  • Patent number: 8122617
    Abstract: A shoe with retractable metal spikes on a heel area is herein disclosed. A bottom portion of a shoe heel comprises a plurality of metal spikes that retract in and out via a cam plate, driven by a cam lever and activated by a control dial located on the outside face of the heel. When the metal spikes are extended, they can be used to walk safely on snow and/or ice, and can also be used in wintertime sporting events. The metal spikes can be retracted by simply turning the dial and allowing them to retract flush or slightly below the surface of the shoe sole. The invention is viewed as being particularly useful for those in construction, public service, law enforcement or any profession in which walking outside in winter conditions and walking inside on finished floors is a regular and repeating part of their work day.
