Abstract
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.
