EMU Australia's STINGER REEF, black, a comfortable pair of sheepskin boots made with wool and suede. - Brand: EMU Australia - Model Name: STINGER REEF - Color: Black - Condition: Used - Material: Wool/Suede I wore these last winter. Although the black color doesn't make them very noticeable, there are wrinkles from wear, pilling on the shearling, and some wear on the soles.
