I had almost given up hope of finding inexpensive navy flip flops when I saw these. I ordered a 7, but a 6 would have been a better fit. That was my decision - it doesn't reflect on the product. The soles are pretty slippery at first, but when they are scuffed/roughed up a bit there's better traction. I kept them because the color is exactly whan I wanted and they seem to be pretty sturdy. My biggest complaint is the rough underside of the "ribbon" at the top of the thong. I do love the color, so much so that I'll be wearing bandaids on that part of my foot until the material softens or my skin toughens up.
