A pair of roller skis each comprising at least four fixed rollers disposed in parallel on the central lower face of a long and narrow board made of an elastic material while having a left-right spacing corresponding to the width of the board and while having a front-rear spacing shorter than the front-rear length of a boot secured to the board, and two casters, one disposed on the lower face of the top portion of the board and the other disposed on the lower face of the tail portion of the board, wherein when the board is placed on the ground with no load applied thereto, only the rollers of the top and tail casters make contact with the ground and the fixed rollers at the central portion are away from the ground. With this configuration, it is possible for the user to enjoy or practice skiing on slopes with no snow while having sliding feelings and using sliding techniques similar to those of snow skiing.
