1. An ice skate for skating on ice, which ice skate comprises;
an upper chassis section comprising a first contact surface having a front end and a rear end,
a lower chassis section comprising a second contact surface having a front end and a rear end, and
a coupling arrangement comprising a spring back means, which coupling arrangement is arranged to mechanically connect the upper and lower chassis sections,
wherein at least one of the first and second contact surfaces is curved,
wherein the coupling arrangement is arranged to allow the upper chassis section to pivot relative to the lower chassis section by rolling contact motion between the first and second contact surface such that a momentary contact region (CR) of the first and second contact surfaces moves back and forth between the front and rear ends of the first and second contact surfaces,
wherein the spring back means is arranged to urge the momentary contact region to a neutral position which is located at the front end of the first and second contact surfaces, and
wherein the spring back means is entirely arranged in front of the front ends of the first and second contact surfaces.
