FIELD: sole for sportive shoes, in particular. ^ SUBSTANCE: sole is tangentially deformed for at least 20% of its deformable thickness and becomes substantially hard with respect to tangential deformation only after at least one critical deformation in zone deformed to such extent. Critical deformation is reached only after passage of tangential and/or perpendicular deformation path which exceeds 20% of its deformable thickness. This path may exceed even more than 50% of this thickness. Sole is sufficiently soft and pliable in tangential direction too. This feature allows runner to reach stability in any point of stepping by foot or loading it. Runner may spring again from loading point without path loss. Sole may be detachably attached as integral part or as a plurality of parts to intermediate shoe sole. ^ EFFECT: simplified construction, elimination of floating effect, and improved deformability properties of shoes using such sole. ^ 14 cl, 20 dwg |
