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).

A stability system is formed from a support wedge having a bottom, an inner surface and an outer surface and a bottom platform connected to the bottom of the support wedge and extending past the inner surface to create a space for receiving a bottom of the shoe. There are attachment devices connected to the support wedge and bottom platform for connecting the stability system to a shoe. The support wedge is formed from an elastic material that compresses to a predetermined degree upon application of a downward force, such that the stability system exerts increasing resistance as the downward force increases.
