A garment for muffling sound generated by a user`s footstep includes a circumferential sidewall having an upper end, a lower end, and a circumferential lower portion near the lower end. When the garment is worn, the upper end encircles the user`s leg, and the lower position surrounds the user`s foot and shoe portion that surrounds the foot. The lower portion has a circumference substantially larger than the circumference of a user`s shoe, whereby the lower portion is spaced away from the user`s shoe during at least part, if not all, of a user`s footstep. In this fashion, the garment creates an enlarged chamber for muffling sounds generated by the user`s footstep.
