Abstract: A diagonally twisted sole may include an undersole and a midsole bottom, the midsole bottom being connected to the undersole, and various hard inserts being able to be introduced into the undersole. Together with a twisted, flexible, rigid or elastic plate, the undersole can form a midsole, which may include several parts. The twisted plate may be a flat plate or a plate of different thicknesses.

Abstract: A device for active rolling walking (1) includes a conventional upper shoe (2) used for fixing the device to the foot, which upper shoe can be made from leather, textiles or other natural or synthetic materials, and a specially constructed sole to force active, rolling walking to take place and can be adapted to all possible circumstances. The structure of the sole and the choice of material gives the user, when rolling, the feeling of walking bare foot in the sand with a trampoline effect.

Abstract: A shoe includes a sole (2) that extends from a rear heel area (6) through a metatarsal area (7) to a front ball or toe area (8), the sole being composed of a sole body (10) and a sole covering (11) formed on the underside of the sole body (10) and a recess (13) extending approximately from metatarsal area (7) to heel area (6). The recess is provided between sole body (10) and sole covering (11), with the area of sole covering (11) associated with recess (13) forming a pivoting element (18) designed to pivot around a pivot axis (20) located in the end area of recess (13) facing metatarsal area (7). The end area of recess (13) facing metatarsal area (7) is defined by a tip (13a) of recess (13), and the pivot axis (20) is located in the area between a lengthwise center of shoe (1) and heel area (6), with heel area (6) extending over approximately one-third of the length of shoe (1).
