  • Patent number: 8539698
    Abstract: A footwear traction device is disclosed that enhances regular or slip-resistant shoes during a slip-in-progress. The traction device includes an adhesive layer embedded with microscopic friction additives, natural or engineered, and partially covered with an epoxy resin in a design that pierces and grips the microscopic roughness of a surface and any contaminants thereon, providing emergency traction during a slip. The footwear traction device provides more than one opportunity to recover from a slip and regain traction. In the event that a fall is unavoidable, the footwear traction device provides a first and a second push back force, spreading the force of the fall over a larger area, minimizing the absolute force of the fall and providing a safer trajectory during the fall. The slip recovery method and system of the present invention offers an economical solution that reduces the financial and human toll caused by slip-and-fall accidents and deaths.
