<p>The sole (200) has a front foot zone (A), a heel zone (C), and an arch zone (B), where the heel zone is bent in the extension of the arch zone. The sole is flexible so that the arch zone and the heel zone elastically bend when a user carries his weight on the foot in a loading position, where a transversal section of a contact surface (205) in the heel zone is oriented along a direction of the heel. The sole is formed from a plate which is made of thermoplastic material e.g. polypropylene.</p> |
