A balancing disc or appliance for use in with a shoe insole, or biomechanical device, such as an ankle or foot brace, for balancing the gait of a user is defined by a substantially circular disc or body element having a top surface and a bottom surface. The top surface and the bottom surface are angularly inclined with respect to each other in an angle ranging from about 2.degree. to about 6.degree.. Optimally, an adhesive is deposited onto one of the surfaces for facilitating affixation of the disc to an insole or similar orthotic device. The disc is, preferably, formed from a flexible material. Since the device is substantially circular in nature, it may be rotated about a vertical axis through a 360.degree. arc to facilitate minute adjustments in the balance of the user.
