Abstract:
1. An ice skate, comprising: a sliding surface for sliding along an ice surface, the sliding surface comprising a concave surface with middle and sliding edges; the sliding surface further comprising profiled grooves, whereby at least one profiled groove is provided in the middle, forming central sliding zones, and other profiled grooves near each of the sliding edges form outer sliding zones; and the profiled grooves comprising transverse force transmitting bulge-like dams having rounded-off diameters protruding from the sliding surface on either side of the profiled grooves, and the profiled grooves and the bulge-like dams extending in a direction of movement, such that the central sliding zone and the outer sliding zones are configured to prevent loss of a water film created between the sliding surface and the ice surface and to maintain a constant water film under different dynamic loads, wherein the profiled grooves are deeper than the sliding zones and the outer sliding zones, and wherein the sliding surface further comprises an interchangeable sliding blade.
