FIELD: personal use articles.
SUBSTANCE: sole, in particular for sport shoes, may be arranged with higher elastic deformability also in tangential direction forward and backward, as a result proper shock absorption is also achieved during inclined and slightly shifting treading. However, after critical deformation has been achieved in such deformed area, sole is substantially rigid relative to tangential deformation. Runner may again push off load point, also without losses in distance. According to invention, elastic deformability of sole is achieved also in tangential direction as a result of at least one first element, and its mentioned rigidity against tangential deformation after achievement of critical deformation, as well as extent of critical deformation in such deformed area is identified by at least one second element. While these first and second elements may be independently calculated, identified by size, there are more opportunities for practice regarding design, improvement and changes. Finally, in the area of heel and/or toe of sole there are multiply alternating zones, identified with at least one first element and zones identified with at least one second element.
EFFECT: provision of opportunity to avoid floating effect in case of high elastic deformations.
