Vintage 80s Foam Flip Flips (size 10/11)

Vintage 1980s foam flip-flops used condition there is no size listed however I wear a size 9 and I tried them on. I’m estimating them to be between a size 10 and 11. I did place a photo with measurements. Please see all pictures. These have been hand washed and air dried. They do have a chunk taken out of the back of one of the heels on the bottom, and there is suede and nylon straps. Overall, still in usable condition sold as is. Bin: D61 shoes
