Abstract
The shoe is a foldable shoe with sufficient rigidity during use but allows for folding during periods of non-use. The shoe has an upper which is made of a flexible material that makes it possible to push the upper together in the longitudinal direction of the shoe. In a portion of the shoe there are reinforcing elements which run perpendicular to the longitudinal direction of the shoe and maintain the form of the shoe in a direction perpendicular to the longitudinal direction of the shoe. Rigid material is formed around the toe area and the heel area of the shoe. To make the shoe sufficiently rigid for use, an outer element that clamps onto the reinforcing elements, a stiff insole, or both is used.
