The present invention relates to an assembly to improve the stability of a user of the assembly, the assembly comprising: a brace for connecting to a lower leg portion, the brace comprising a stabiliser connecting portion and a stabiliser for connecting to a shoe, the stabiliser comprising a brace connecting portion and an extension portion having a shoe connection portion configured in use to connect the extension portion to the shoe so that the extension portion extends laterally from the shoe to increase the effective surface area of the shoe sole at only a lateral side and to improve the stability of a user of the stabiliser, wherein the brace and the stabiliser are couplable together by the stabiliser connecting portion and the brace connecting portion so that, when said lower leg portion is connected to the brace and said shoe is connected to the stabiliser, an outward lean of said lower leg portion with respect to said shoe is limited to a predetermined angle, thereby providing a stabilising force to improve the stability of a user of the assembly, and wherein the stabiliser connecting portion and the brace connecting portion are uncoupled during normal locomotion of a wearer of the assembly, thereby providing unimpeded movement for normal locomotion.
