Genuine Japanese Zori Sandals.
These zori have black velvet thong toe straps and are sold in inch sizes. (NOT shoe sizes).
To find your size stand barefoot on a piece of paper and outline your foot keeping your pencil perpendicular to the paper. Measure the tracing with a ruler from the tip of your big toe to the end of your heel and round up to the nearest size.
The top of the zori is a vinyl type material with a rubber sole. Enjoy these zori indoors or outdoors!
