To solve a problem that a carrier bag having a grip is used for carrying ski boots, however the material is restricted to a strong one such as nylon bearing the load of the ski boots, thereby the bag is bulky when storing and moving it and there is no appropriate cover when connecting power belts of the ski boots to each other and carrying them.

Cover bodies 1 for ski boots for storing and protecting left/right ski boots separately are mounted thereon respectively. The cover has a sock shape corresponding to the external shape of the ski boot, has an opening part 4 with an opening/closing means at the cover rear back part and is formed with a portion for passing the power belt 6 of the ski boot therethrough at the upper part of the opening part. The opening/closing means of the opening part is divided into two, and an interval portion having no opening/closing means is provided near the center of the opening part. A fold line to be the sole part of the cover is not sewn and has a flat structure. Female/male hook-and-loop fasteners 2 which are easily attached/detached by a user with gloves in the cold district, are used for the opening/closing means of the cover opening part. Fleece fabric is used as the material.
