  • Footwear having retractable spikes
    Patent number: 4375729
    Abstract: Anti-skid spikes for use on shoes or boots, to provide firm footing on ice or snow. The spikes are readily extendable and retractable without the use of keys or tools, e.g., when entering a car or a house where floors and rugs might otherwise be damaged thereby. A mechanism for selectively extending and retracting the spikes is sealed within the sole and heel of the footwear to provide improved esthetics and to prevent interference with the mechanism, as by moisture and ice, when temperatures vary from hot to cold.
