Die Erfindung ist gekennzeichnet durch die Kombination folgender Merkmale:The invention is characterized by the combination of the following features:

a·) eine abriebfeste Ummantelung (Aussenschicht) von unterschiedlicher Stärke vorzugsweise mit Spitzen- und/oder Absatz- und/oder Laufflächen-(Profil-)Verstärkung a ·) an abrasion-resistant casing (outer layer) of different thicknesses, preferably with Point and / or heel and / or tread (profile) reinforcement

b.) eine leichte poröse aus hochelastischem Schaum, in an sich bekannter Weise eine Verbindung zwischen Ummantelung (Aussenschicht) und Schaft bildende Zwischenschicht·b.) a light porous made of highly elastic foam, in a known manner a connection between Sheathing (outer layer) and intermediate layer forming the shaft

Durch die vorgenannten Erfindungsmerkmale wird es ermöglicht, ein Schuhwerk herzustellen mit einer echtem Luftpolsterwirkung aufweisenden Sohle, die aber gleichzeitig in besonders vorteilhafter Weise so ausgebildet ist, dass sie auch an den hochbeanspruchten Stellen eine lange Lebensdauer aufweist.The aforementioned features of the invention make it possible to produce a shoe with a genuine one Sole having an air cushion effect, but which at the same time is particularly advantageously designed so that it also has a long service life in the highly stressed areas.

Nach einem weiteren Vorschlag der Erfindung ist vorgesehen, dass der Absatz Versteifungsstege aufweist und/oder in dem. Absatz ein an sich bekanntes Füllstück vorgesehen ist.According to a further proposal of the invention it is provided that the paragraph has stiffening webs and / or in the. Paragraph a known filler is provided.

Die Erfindung kann in verschiedener Weise durchgeführt werden« Ausführungsbeispiele sind zur Veranachaulichung in der anliegenden Zeichnung dargestellt.The invention can be carried out in various ways « Exemplary embodiments are shown in the accompanying drawing for illustrative purposes.

Wie aus Figur 1 ersichtlich ist, die ein Schuhwerk Io teilweise im Schnitt wieder gibt, besteht dieses in üblicher Weise aus einem Schaft 11 mit einer angeformten mehrteiligen Sohle 12 aus Gummi oder Kunststoff.
