NWT Silver glittery LED multicolor light up unisex high top sneakers size 37/US women’s 6.5 They are not marked with US sizing. I usually wear a women’s 6.5-7/mens 5.5 and they fit fine. Never been worn. Comes with USB adapter to plug in shoes for the lights. They look pretty cool, I ordered 2 different pairs and this one came in too late for my event.
