The top (12,14) of the stable, block-shaped basic body (11) has fastenings (16,17) attaching it below the foot or shoe. The height of the block is roughly half that of the step. The fastening incorporates an inflatable foot, or shoe pad, that may be integrated in a foot or shoe top part. The inflater can consist of a connecting tube, rubber pump and inlet and outlet valve. The underside (13) of the basic body may be made of non-slip material such as cross-profiled rubber (15). The top (12) of the basic body can be coated with non-slip elastic material (14) such as cork or rubber. |
