A shoe sole is composed of particles of Ethylene Vinyl Acetate and the particles are connected with each other with gaps defined between the particles so as to form irregular surface of the shoe sole. The sole is made by filling the particles to 77% to 87% of volume of a cavity in a mold set, wherein an angle 40 to 50 degrees is clamped between a spinning axis of the cavity and an axis to which the mold set is rotated about. The mold set is then heated to 140 to 160 degrees Celsius and spins the mold set about the spinning axis 22 to 32 minutes. After cooling the mold set, the shoe sole is formed and is removed from the cavity.

The present invention includes a retractable signaling apparatus and a method of using the apparatus to alert passers-by to the presence of a stationed vehicle that may be obscured from view. In situations that include the parking of a small vehicle or the stationing of such a vehicle along a road due to mechanical difficulties, it is often difficult for passers-by, including pedestrians and other motorists, to be aware of the presence of the vehicle. In such situations the present invention provides an easily carried signaling device that can be tethered to the vehicle. The signaling device provides an alert to passers-by of the presence of the vehicle in a timely manner such that collision with the vehicle can be avoided. The tethering means ensures that the alert is maintained in view of ambient conditions or mischief that could otherwise cause the loss of the alerting device.
