Embodiment Construction

[0034] figure 2 The sandal 1 shown in has a midsole 2 into which the valve element is integrated. The valve element 7 makes it possible to initially fill the fluid medium in the midsole and, as the case may be, to replenish or replace it thereafter. Preferably, the valve 7 is of self-closing design but it can also be closed by means of a plug or can be closed by welding. In the latter case, the sole cannot be refilled.

[0035]The sandal itself is provided with a strap structure 6 securing the sandal to the wearer's foot, said structure being anchored in 2 / 3 of the sole structure via two rear fasteners 4 and one front stabilizer 5 . The fasteners 4 and 5 extend through the midsole 2 and into the outsole 3, and they are anchored in the outsole 3 by means of a disk-shaped enlargement 8 (see figure 2 , 3 ). It is easy to see that the fasteners 4 and 5 extend through ducts arranged in and through the midsole 2 that make it possible to achieve a protective shell that is impe...

Abstract

The invention relates to footwear, the sole of which has a multilayer structure, i.e. at least one outer sole (3), an optional inner sole, and an intermediate sole (2) that is made of an elastic material having an open cell structure which is provided with a gas-tight and liquid-tight outer skin and which is filled with at least one fluid medium.

Description

technical field [0001] The invention relates to footwear comprising a sole of at least two-layer construction, wherein said sole consists of a harder outer sole (outsole), an optional softer inner sole (insole) and an elastic middle sole (midsole) . Background technique [0002] During running, the musculoskeletal system is and must withstand considerable loads. Over time, many runners (even those who do not engage in competitive sports) are prone to suffer from knee and joint problems that can be detrimental not only during exercise but also in terms of daily movement and exercise. could cause serious trouble. In view of counteracting the aforementioned loads, cushioning elements for footwear have therefore been developed. [0003] For running shoes, a considerable number of cushioning concepts have been developed. [0004] For example, the company Nike has developed a system based on air soles. For this purpose, an inflatable air cushion is integrated into the sole of...
