<p>An aid for walking on a slippery urbane environment, for example on ice and snow, enables a simple and fast - also for elder persons - attachment to an optional type of shoe and assures a safe walk over a slippery ground. The aid is carried out of a slip-proof plate (1) fitted with a quantity of teeth (2) or similar directed towards the ground (A) to provide a grasp of the plate (1) to the base such as ice and compressed snow. There is another slip-proof plate (3), carried out with a plenty of teeth (2) directed towards the sole (B) of the shoe (C) or with other means assuring a grasp to the sole (B), and a band (4) forming a closed loop together with the plates (1 and 3). The length of the band matches approximately the circumference of an optional shoe (C) around the instep, and the band (4) is carried out at least partly, but preferentially completely of an elastic material, which assures a tight adjustment of the shoe.</p> |
