At the lower end of a pair of skis (S) there is added a rolling device which has a removable fixable support (1) as well as a free wheel (2). The support may be introduced between the two skis until its lower stop edge (9) meets the lower edge of the skis. For the lateral support, additional stops (10 to 13) are provided. The fixing of the support is effected by means of a conventional attachment strap (3), of which the steel hook hooks in the groove provided in the support. The wheel (2) is thereby fixed to the skis and slightly protrudes beyond the lower edge thereof. |
