摘要

The invention relates to a shoe that comprises at least one extension spring element (18), disposed between projections (44, 46) of a heel area (48) of the shoe (4) and a shaft area (46) supported on the front of the shinbone (50), that extends during the pace phase. According to the invention, a tensioning device (100) is provided and displaces the projection (44) of the extension spring element (18) in the heel area (48) away from the projection (46) in the shaft area when the shoe (4) is placed on the ground, thereby extending the extension spring element (18).
