ABSTRACT:
A first body for attachment to the undersole portion of a shoe is provided and includes front and rear marginal portions. A second body for underlying the heel portion of a shoe is disposed to the rear of and swingably supported from the rear marginal portion of the first body for swinging relative thereto about a horizontal transverse axis. A spring is operably connected between the first and second bodies and functions to yieldingly upwardly swing the second body relative to the first body and the first body includes a downwardly facing bearing member journalled for rotation about a horizontal axis as well as an upstanding axis. With the first body suitably attached to the forward undersole portion of a shoe, the wearer of the shoe may propel himself with his other shoe and, upon transferring his weight to the shoe from which the first body is supported, roll across a suitable supporting surface. The second body, upon upward flexing of the heel portion of the associated shoe, is swung upwardly out of engagement with the supporting surface, but may be downwardly displaced by the heel of the associated shoe into engagement with the supporting surface for braking action.
