Problems solved by technology

[0016] [16] Some completely sealed footwear constructions also exist, such as rubber boots constructed of sealed, poured, and welded materials, but these boots are completely incapable of expelling any moisture and are therefore uncomfortable and unpleasant to wear
In addition, such boots generally do not include locking components, so they are hardly usable for sports such as walking and running

Embodiment Construction

[0030] [30] Fig. 1 shows a piece of footwear, such as a sports shoe 1 consisting of an outer upper 10 and an outer sole 2. The upper 10 of a shoe can be installed on the outer sole 2 by any known technique such as pasting, repeated pouring, etc.

[0031] [31] The upper 10 is basically a soft upper, i.e. formed from some main parts of soft or relatively soft material, but also includes some supplementary parts of rigid or semi-rigid material used to shape the shoe and, if necessary, a Inside the upper 10 and shown in dashed lines in FIG. 1 is a heel counter 11 and a toe cap 12 located at the end of the upper 10 and simultaneously serving to shape said upper 10 at the toes and to protect the upper 10 . In the whole shown, the toe cap 12 is a cast TPU, PU, ​​PVC, fabric or rubber toe cap glued directly to the upper before assembly to the outsole 2 .

[0032] [32] Depending on the embodiment and / or the type of footwear, the toe cap 12 can be provided in the footwear like the heel ...

Abstract

The shoe has an external sole (2) on which an external flexible upper (10) is disposed. The upper has a vamp (13) and a backer (16) that are assembled by stitching and made of breathable waterproof material that is constituted of a layer made of treated extensible material, another layer constituted by a breathable-waterproof membrane e.g. plutonium (PU) film known under trade description of Sympatex(RTM: Not defined) and a third layer made of polyester or polyamide mesh. Apparent stems (16c, 17) of the upper are covered by a sealing band (18) disposed at the exterior of the upper.

Description

technical field [0001] [01] The present invention relates to the aspect of footwear, in particular breathable-tight sports shoes, walking shoes, running shoes. Background technique [0002] [02] By seal, here is meant a seal or waterproof shoe, ie a shoe whose at least one functional layer of the upper constitutes at least a barrier to the ingress of water or liquids. Breathable-sealed means that the footwear allows water vapor (sweating) from the foot to pass outwards while sealing it against water from the outside world. [0003] [03] Footwear traditionally consists of an outsole, which may be soft or hard, on which is mounted an upper covering the user's foot. [0004] [04] The upper should form a three-dimensional shell that approximates as closely as possible the shape of the user's foot. This upper is formed most of the time in the form of several parts which are cut and assembled together by stitching to form said three-dimensional outer shell. The shape of these p...
