No grey areas here! We simply LOVE the Bamboo Grayson 01 Black T-Strap Thong Sandals! A black faux leather strap forms a thong-style vamp that sweeps back into a crisscrossing T-strap, with a silver metal accent in the middle of the action. Cupped heel has a 2.75" heel zipper. 1/4" rubber heel. Smooth genuine leather insole. Non-skid rubber sole. Available in whole and half sizes. Fit is true to size (round down if you're between sizes). Measurements are for a size 6. Leather insole. Upper and balance man made.
