A stabilizing training device suitable for use on an ice-skate is disclosed. The device provides a foot retaining portion and a stabilizing portion directly under the foot retaining portion. The unit is designed to provide at least partial resiliency to permit limited lateral movement in use. The device is positioned about the foot or footwear by positioning the former into the foot retaining area. A base extends between foot retaining members of the foot retaining area. The base contacts the sole of the foot or footwear and has, extending downwardly and outwardly therefrom, arms which provide for the stabilizing aspect when the device is in use.
