Abstract
According to the invention a heel binding is envisaged which gives the possibility of a positive contact between the heel of the shoe and the cross country ski within the natural limits of the elasticity of the components being used. According to this invention this function is resolved by two parallel, swivel mounted stirrups, one of which serves as a tensioning stirrup and the other as an operating stirrup. Through the swivelling of the same it is possible to engage or release the binding.
