FIELD: sports.
SUBSTANCE: invention concerns ski sports. Skating ski feature sliding surface, stock part to assume elastic deformation from dynamic load by foot push, and bearing area connected to stock part by joint. Sliding surface is made in the form of replacement modules fixated at skating ski so as to shift along the ski length, and stock part is made in the form of friction pad attached to sliding surface so as to contact trek by foot push. Bearing area is made in the form of coupling link with crankshaft attached by joint to loose link end and interacting pivotally with slider mounted on skating ski with linear movement control.
EFFECT: enhanced efficiency of skating ski usage on running treks, maximum reduction of ski length in running mode, convenient carriage, transportation and storage.
