Attachment for an in-line skate of the kind having a plurality of linearly-aligned wheels comprising chocks which arrest rotational movement in adjacent wheels at the front of the skate and at the back of the skate. An elastomeric member biases the chocks in operative alignment and joins them so that they can be spaced from each other to receive a selected number of wheels in-between. The elastomeric member has first and second end loops which are fastened to respective ends of the associated skate.
