• three skis comprising a first ski, a second ski, and a third ski;
• a standing device which is configured to have a user stand thereon, wherein the first ski and the second ski are arrangeable on the standing device next to each other in a direction of travel so that the first ski is available for a first foot of the user and the second ski is available for a second foot of the user;
• a holding device which can be held by at least one hand of the user;
• and
• a frame which is configured to connect the standing device to the holding device, the frame being connected to the standing device in a relatively movable manner,
• wherein,
• the frame and the standing device are configured to be foldable relative to each other so that a required spatial volume of the ski winter sports device can be reduced,
• the standing device comprises a first mounting frame part and a second mounting frame part which are each configured for arranging at least one of a foot receiving device and one of the first ski or the second ski, and a parallelogram guide which is configured to synchronize an inclination of the first mounting frame part and the second mounting frame part and thereby the first ski and the second ski transversely to the direction of travel,
• the parallelogram guide is a parallelogram linkage or a gear of a four-bar linkage, the respective opposite links of which are of an equal length,
• the parallelogram guide comprises a first component, a second component, a third component, and a fourth component,
• the first mounting frame part comprises at least one frame member which comprises a first frame member of the standing device and a second frame member of the standing device,
• the second mounting frame part comprises at least one frame member which comprises a first frame member of the standing device and a second frame member of the standing device,
• the third component is rotatably arranged on the at least one frame member of the first mounting frame part, and
• the fourth component is rotatably arranged on the at least one frame member of the second mounting frame part.
