or upper leather, injected a synthetic resin into the j clearance or gap to fill it ί and the liquid is cooled and solidified so that the leading edge and the synthetic resin layer and the intermediate floor layer or Kauptbodenschicht be firmly connected to each other. By correct selection of the material of the intermediate floor layer or the main soil layer becomes the problem of twisting, deformation or deformation or peeling or peeling of the Overcome the shoe bottom and a warm, wet-proof, waterproof, durable, abrasion-resistant or against cold, tried and tested Wear resistant, flexible and elastic that Obtained the required stiffness shoe, with which one long time on roads with poor conditions can walk comfortably. The method also saves the labor of sewing the bottom, thus making products more uniform Goodness or mountaineering shoes or climbing shoes or other street shoes or sports shoes with a lower cost.

Injection molding process for the production of shoe soles, with which formed a shoe sole made of synthetic resin is to be done by attaching an instep or shaft leather in a metal mold, a synthetic resin liquid in the metal mold. injected and filled the metal mold with it and the Liquid: hermetically coupled to the instep or upper leather part will, are on the. Area of climbing shoes or the like. well known. The one made by this process Sch jr. wears off easily because its sole is made of synthetic resin and is too soft to crawl. Furthermore, since it is impossible to use - <iete or to change the shoe sole, is i: ie for o '; egg ~ shoes unsuitable.

The main aim of the present invention is the Schaffving eiX'BS process for the production of shoes that are suitable are for climbing or running or as sports shoes by using the injection molding process.

Another object of the present invention is to provide a climbing shoe or other sports shoe with more waterproof (more waterproof and moisture-proof) Property and flexibility that are characteristic of the injection molding process mentioned while at the same time good running properties and wear resistance can be achieved, which is "in the case of the injection molding process shoes manufactured according to the state of the art has been considered impossible, and further according to the invention the replacement of a shoe sole and riveting on the shoe sole is made possible.

Another object of the present invention is to provide a sturdy sports shoe, thereby eliminating a shortcoming such as peeling off or wearing away or tearing off the sole as a result of the difference in extension and contraction between the sole and a synthetic resin layer due to temperature change or impact or the like.

The method according to the invention for the production of shoes will now be described in more detail with reference to the accompanying drawings.

An inventive sport shoe is formed by a flat-shaped intermediate base layer 2 or the main bottom layer of synthetic rubber, leather od. Like. Spread a bottom forming mold Λ over iron inner bottom of a mold cavity, an instep or shank leather mounted on the upper part of the mold cavity and fixed, so that the lower front edge 5 of the instep leather 4 lies within the mold recess, a clearance or gap 6 is formed between the intermediate floor layer 2 or main floor layer 3 and the lower front edge 5 of the instep leather 4, a synthetic resin liquid is injected into the gap 6 to fill it and the Liquid is cooled so that it is solidified, the front edge 5, the Kunstharζschicht 7 and the intermediate floor layer or the main floor layer 3 are all verburden with each other during this procedure.

The one produced by the process of the invention Shoe has the intermediate layer 7 made of synthetic resin, which is located at the space between the lower front edge 5 of the instep

leather 4 and the intermediate floor layer 2 or the main floor layer 3 is formed. Due to the fact that the synthetic resin liquid in the false floor layer 2 or the main soil layer flows into it, becomes the lower The front edge 5 of the instep leather 4 is completely covered, with the aid of the in the course of cooling and solidification of the Synthetic resin fluid made binding the instep leather and the intermediate floor layer 2 or the main floor layer are firmly connected by the synthetic resin layer 7 so that Defects such as twisting, deformation or change in shape and peeling off of the shoe bottom can be avoided and the Shoe according to the invention is often superior, since it is protected against the cold and warm, compared to the after state-of-the-art climbing boots, Street shoes or other street shoes.

In the novel production process of the material of the intermediate base layer 2 or H _a a climbing shoe or any other sport or StraJ can uptbodenschicht by proper selection of 3 without difficulty? Are made enschuh, which is characterized by its waterproof riding (wet strength and water safety) and durability. The shoe produced by the method according to the invention thus has an intermediate floor layer 2 or main floor layer 3 a ^ .f, which are arranged directly below the synthetic resin layer 7 one above the other, so that the outer peripheral edge of the synthetic resin layer 7, which is weak against friction with a stony surface, is protected against wear is. Such a construction also results in a corresponding flexibility together with the necessary rigidity for the floor so that, together with a corresponding cushioning effect or federr.de effect of the synthetic resin layer 7, it also provides a comfortable reaction for

yields the one who puts his shoes on flat when he walks on bad roads for a long time. With your shoe according to the invention there is also the replacement and Riveting of the shoe bottom is possible, which is impossible with the prior art injection method has been considered.

In the shoe produced according to the method according to the invention, the intermediate floor sub-layer 11 or intermediate floor sub-rail 11 and an intermediate device or, the intermediate clamping device or fastening device (see Fig. 1) and the intermediate floor layer 2, the intermediate floor sub-layer 11 or the intermediate floor sub-layer and the intermediate clamping device and the intermediate floor layer 2 and the main bottom layer 3 by the cooling and solidification and migration of the synthetic resin liquid injected into the space between the intermediate bottom layer 2 or the main bottom layer 3 and the lower front edge 5 of the instep leather 4, so that the work of sewing the bottom is saved and enables wire !, products of the same quality to be obtained at lower costs. ”Here it should also be noted that such a construction reduces the difficulty due to the penetration of water at the sewn-on edge of the floor ns of the climbing shoe or another street or sports shoe is completely overcome. For the injected part in the injection molding process according to the invention, synthetic resin can be used as the raw material and the wipe floor layer 2 and riie floor floor layer 3 - u .. ^ !, egg ¹ , an enamel layer ;, riur.s'bfiiT o 'e: · "· a, anchor preeigenten material to be made.
