Abstract: An insole is proposed for a shoe. The insole has a lower side configured to face a shoe outsole, and an upper side opposite the back side for contacting the sole of a shoe wearer's foot. A projection projects upwardly from the upper side. The insole is configured to position the projection at a location of the user's foot directly under a medial side of the cuboid bone. A kit for assembling an insole for a shoe is also provided. A method for treating a disorder of the foot is further provided.

Abstract: An outsole for a shoe, at least a portion of the outsole has a grid structure of intersecting lines along the course of which the outsole has increased flexibility The grid structure is irregularly formed by lines which are determined on the one hand at least by the course of the connecting curve through the toe joints between the distal phalanx and the proximal phalanx of the big toe and between the respective middle phalanx and proximal phalanx of the second, third, fourth and toes, and on the other hand by the course of the respective intermediate spaces between the five toes when the sole is positioned to fit under the wearer's foot. In the same way, a shoe having an outsole of the kind described above is also proposed.

Abstract: An insole is proposed for a shoe. The insole has a flat back side in direction of the shoe outsole and a dome-shaped structure on the front side. The dome-shaped structure has a base surface of a maximum of 25% of the insole surface; the dome-shaped structure is positioned under the cuboid bone of the shoe wearer. A longitudinal axis can be associated with the dome-shaped structure at its apex, wherein the longitudinal axis of the dome-shaped structure encloses an angle (?) in a range from 5° to 75° with the longitudinal axis of the insole.
