Claims1
A shoe traction apparatus consisting of:
- an elongated strap member provided with releasable engaging means on opposite ends;
- an upper frictional unit formed on the top of the strap member intermediate the ends;
- and,
- a lower composite frictional unit formed on the bottom of the strap member intermediate the ends;
- wherein, the composite frictional unit comprises a relatively hard frictional component and a relatively soft frictional component;
- wherein, the relatively soft frictional component partially and wholly surrounds different portions of the relatively hard frictional component, and, wherein, the relatively hard frictional component comprises a plurality of discrete edible seed particles;
- whereby individual edible seed particles will become disengaged from the relatively soft frictional component at intervals during use to provide a food source for birds.
