Abstract: An ankle foot orthopaedic apparatus (10) includes a sole (66), a control part (18), and a connection arrangement (16) for connecting the sole (66) to the control part (18) for controlling or guiding the orientation of the sole (66) in use. The sole (66) includes a sole connector part (20), which comprises part of the connection arrangement (16). The control part (18) includes a control part connector part (22), which comprises part of the connection arrangement (16). The connection arrangement (16) permits movement of the apparatus (10) between a connected condition, in which the sole (66) is connected to the control part (18), and a disconnected condition, in which the sole (66) is disconnected from the control part (18).
