A position indicator assembly (45), including first and second positioning units (47, 48), is attached to a pair of shoes (2) in positions which are spaced when the shoes are aligned together. Each positioning unit (47, 48) includes a first proximity switch element (70), at least one indicator (72, 73), a battery (74) and a second proximity switch element (75). The battery (75) is electrically connected to the indicator (72, 73) when the first proximity switch element (70) of one of the first and second position units (47, 48) is arranged a predetermined, spaced distance from the second proximity switch element (75) of the other of the first and second positioning units (48, 47) in order to provide a visual and/or audible indication to a wearer that the pair of shoes (2) are on the correct feet. |
