<p>Several narrow flexible elements (10) are inserted laterally at the front of the rigid shaft (6) of the shoe. A rope (3) joined to a counter bearing (4) at the front is guided inside a duct along the sole (1) of the shoe and around a return pulley (5) at the heel to a tightening lever (8). The lever (8) has a u-shape and is held with its transversal segment at the upper edge at the rear of the shaft (7). The rope (3) is tightened within limits when the heel is lifted. The tension can be predetermined with an adjusting element (9) attached to the lever (8).</p> |
