In addition, the carrier trains footwear in the form of a sandal, which as well as in the shoe described above, the tendency is prohibited for pronation or subinjection.

By active walking and the physiologically correct Rolling action activates different muscles much more than with conventionally designed sandals. this in turn is of particular importance for the support the lower back muscles and contributes to the stabilization of the pelvis.

At the Walking is also strengthened the abdominal muscles, since the wearer of the shoe according to the invention in the form of a sandal or mule from passive to active walking.

following the invention is based on preferred embodiments explained in detail with reference to the accompanying drawings. Show it:

1 in a schematic representation of a side view of an embodiment of a shoe in the form of a Sandele with a direction indicated by a dotted line foot;

2 a schematic representation of a longitudinal section of a cassette according to a first embodiment, and

3 a schematic representation of a longitudinal section of a second embodiment of a cassette according to the invention.

In 1 to 3 are the same or similar components of a footwear in the form of a sandal or mule according to the invention designated by the same reference numerals. In the schematic representation is in 1 footwear in the form of a sandal and a foot indicated by a dotted line 6 played. For example, the sandal preferably has adjustable forefoot straps 10 , Midfoot strap 11 as well as heel straps 12 on. The forefoot, midfoot and heel straps 10 to 12 are attached by gluing and / or by sewing to the cassette.

In 2 is a schematic longitudinal sectional view of a first embodiment of a two-layered closed cassette 1a played. The lower layer of the cassette 1a is an outsole body 2a with a only in 1 illustrated outer edge 2f made of elastically yielding material. In the sole body 2a are in the heel area 4c and in the forefoot area 4a different height, transverse, aligned to an imaginary "shoe longitudinal axis" functional slats 2c and 2d intended. Here are the at an acute angle to the rear aligned functional lamellae 2c of the outsole body 2a in the heel area 4c higher or longer than the functional lamellae pointing forward at an acute angle 2d in the forefoot area 4a ,

In the midfoot area of the outsole body 2a is a dome-shaped running trough 3 integrated, in which a movable ball 5 lies. Here is the radius of the dome-shaped recess in the tread 3 slightly larger than the radius of the sphere 5 ,

As upper layer of the cassette 1a is a stiff insole 7 provided, which extends from the heel area 4c through a functional transition area 6 between the midfoot area 4b and the forefoot area 4a extends. The stiff insole 7 lies on the functional lamellae 2c in the heel area 4c on and is with the peripheral outer edge 2f (please refer 1 ) of the outsole body 2a connected. According to an advantageous embodiment of the invention, the insole is 7 on a circumferential internal projection 2g the outer edge 2f the outsole body and is connected to the outsole body.
