Bearing structure with a pronounced upward arch

A combination of a downhill binding or downhill ski binding and a ski boot comprising:

• (a) a ski boot which comprises a rigid ski boot shell and a sole of the ski boot comprising a front end of the sole, a rear end of the sole, an upper side of the sole and a lower side of the sole, and
• (b) a downhill binding which comprises a front jaw and a rear jaw,
• (c) wherein the downhill binding comprises a bearing structure for the sole of the ski boot,
• (d) the bearing structure having an apex, wherein the apex exhibits a perpendicular distance from the upper side of the sole of the ski boot held in the downhill binding of 19 mm±1 mm in at least one point,
• (e) wherein the apex has a distance, in the longitudinal direction, from the front end of the sole held in the downhill binding of at least 28 mm and at most 34 mm,
• (f) wherein an upper side of the bearing structure is not in contact with the lower side of the sole of the ski boot behind the apex in the skiing direction, and a free space is formed between the upper side of the bearing structure and the lower side of the sole, and
• (g) wherein the free space exhibits a distance (Y1) from a lower side of a planar sole of the ski boot according to DIN ISO 5355 of at least 5 mm at a distance (X2) behind the apex in the skiing direction of 20 mm±1 mm.
