These are older NIKE Flip Flops with a Swoosh on the outside of the strap as well as on the toe of the insole. They are Women’s Sz 10 in a Gray accented Black. They have a unisex style so would fit men’s size 8 as well. If you look at the picture showing the inner part of the sandals, you can see the little dashes in the fabric. The right shoe rubs a little - not sure if it’s the shoe or my foot (see first pic of underside compared to left - second pic of underside)… otherwise, I think they’re in very good condition.
