I am satisfied. I bought them this summer and after using them on beaches with rocks, sand, and pebbles, they held up and continue to do so. They do not slip on tiles, marble floors, and in general, they are durable and quite slip-resistant both on the bottom and on the top where the foot steps. Also, the thong area does not bother the toes at all. It is just good to not leave them with salt for too many hours. Salt destroys them all. Finally, in terms of appearance, they are a normal dark flip-flop. If you want colors, go elsewhere.
