Field of the Invention:

The present invention solves the anti-slip sport shoe and the manufacture thereof. The anti-slip sport shoe is intended for various sport disciplines on stadiums with a soft surface of rubber, plastics, etc.

Prior art:

Shoes with spikes have been used for sport disciplines on stadiums so far, but they greatly burden and damage the tendons in athletes' legs and the spikes being pierced into and pulled out result in losses of energy and performance.

The following solutions are known:

EP 18764987.6 (Novak) discloses an anti-slip shoe sole which has pieces of hard material permanently bonded during the manufacture of the sole into the flexible surface of the shoe, and the outer parts of the pieces of hard material protrude from the flexible surface of the sole. The disadvantage of the EP application is that it is only a simple basic definition of the Invention without further specification.

WO 03037128 (Broz) is a commercial adhesive set for customer bonding of particulate material to the surface of a regular shoe sole, and to further surfaces, such as steps, door sills, smooth marble floors, tyres etc. The disadvantage of the application is that bonding particulate material to the surface of the sole of a regular shoe and other surfaces results in problematic quality and anti-slip parameters, and mainly a very short service life, and is thus inapplicable for sport disciplines on stadiums.

The present invention solves the disadvantages and deficiencies of these prior solutions.
