  • Patent number: 4727660
    Abstract: A shoe for rehabilitation purposes, particularly for wear in connection with foot injuries and/or after foot surgery is designed such that patients with foot injuries or after foot surgery can remove rigid supports like plaster casts, orthotics, or the like, in a short time, enabling them to walk again as soon as possible without fear of additional damage or subsequent injuries. To this end, a shoe is provided with an outsole 6 with a front part 8 that extends from the shoe tip 7, which it upwardly embraces, to approximately the toe base joint. The front part 8 consists of an unprofiled material with a low coefficient of friction and is followed by a profiled outsole part 10 comprised of an abrasion-resistant flexible material. The separation line 11 between the two profiled sections 8, 10 extends diagonally rearward from the medial side of the shoe in front of the big toe ball area to the lateral side of the shoe in front of the small toe ball area.

  • Patent number: 4726126
    Abstract: A shoe having an upper portion with a slit opening, through which an insert is placed or placeable into the shoe upper between its upper material and the lining portion, specifically intended for the purpose of rehabilitation, which shoe is designed such that it can be better adapted to various types of foot shapes.The shoe is intended to enable the plaster cast or other support cast, normally necessary in the healing process and employed for foot injuries or foot surgery, to be removed after a short time. This is achieved in preferred embodiments through use of at least one insert 6 of flexible material that has a plate-like configuration. At least one side of insert 6, and a facing inner surface of the shoe upper material coming into contact therewith, has a surface which provides that, at least between these two inner surfaces coming into contact, there is sufficient friction to cause insert 6 to be retained in place during the wearing of the shoe.
