The upper surface of the outsole has at least two depressions being complementary with embossments provided on the lower surface of the insole, allowing a pivoting movement of the front and/or back portion of the insole against the lower outsole surface of the shoe in, at least, an essentially transverse direction to the longitudinal axis of the shoe, when the foot wearing the shoe is pivoted against the ground. To support this movement the insole is more rigid than the outsole and is attached to the outsole.
