Definitions

  • the present invention refers to a water-proof footwear and to a process for its preparation, and particularly to a winter footwear, such as a boot.
  • an internal, functional layer is provided.
  • the inner sole is produced in a material which allows the permeation of the material of the sole in the molten condition and the lower edge of the functional layer is embedded in the sole.
  • a water-proof footwear comprising an internal, functional layer, enclosed in the toe, the toe and the functional layer having different length, characterised in that the edge of both the functional layer and the toe is made of a thermoplastic material and in that both edges are fixed together and the resulting structure is in turn fixed to the sole.
  • a functional layer 2 and an edge layer 3 in thermoplastic material are shown.
  • Fig. 2 The same layers, after connection of layers 3 both to the toe 1 and the functional layer 2 are represented in Fig. 2.
  • the connection above can be obtained in any known way.
  • the most preferred method is by a strobel joint. Otherwise, the layer 3 can be soldered or glued to the toe 1 and to the functional layer 2, respectively.
  • a strobel sole 4 is represented in Fig. 2 before the final assembly.
  • thermoplastic layer 3 is made of a thermoplastic polyurethane (TPU).
  • thermoplastic layers 3 are fixed together and connected to the sole 4.
  • thermoplastic layer 3 - formed by the fixed together, original edge layers 3 - projects from the toe 1 and is bent under the zone where the foot leans.
  • the present invention provides a water-tight construction, which can be both soldered and glued to the sole 4.
  • the connection of the sole to the toe is done by melting the thermoplastic layer 3 and by embedding it into the molten sole.
  • a pre-formed sole 4 is glued to the thermoplastic layer 3.
  • the water-proof layer 3 is glued to the insole.
  • the assemble is glued to the sole. It is apparent for the skilled man that the present invention allows to get a footwear which is water-proof and easy to produce. Furthermore, it is suitable for both soldering and gluing to a sole.
