Abstract: An ice grip is adapted to be worn on a user's foot and includes a sole having a ground engaging surface (2) on which is mounted at least one location element (10). The location element (10) is adapted to removably engage a traction element (20) for improving the traction of a user wearing the ice grip when standing or walking over slippery surfaces. The location element (10) and the traction element (20) are cooperatively arranged such that the traction element (20) is received by and removed from the location element (10) in a plane substantially parallel to the plane of the ground engaging surface (2).
