The skis are intended to convert a stroller temporarily into a sled. Each ski is at least as long as the distance between the front and rear edges of the wheels on one side of the stroller and comprises a flat runner having at least one, preferably both ends curved upwardly and a clamping means on the upper surface of each runner for detachably holding each wheel in position on the ski by providing tension forces on the wheels in opposing longitudinal and lateral directions. Preferably, stop members are provided to prevent lateral movement of the wheels on the skis.
