Abstract: Low gravity is simulated in toy space boots by provision of a cushion attachment for a shoe that includes a reservoir that gives way slowly as the weight of the wearer is placed thereon so that a sinking sensation is produced with each step of the wearer. The cushion attachment is provided with a leveling feature so that the foot of the wearer is substantially level at the end of a step although the wearer has a normal ''''heel and toe'''' stride. The maximum collapse of the reservoir is controlled by internal means. Sound effects associated with the steps of the user are produced by further means incorporated in the attachment.
