A friend of mine left a pair of similar Quicksilver sandals at my house and I took it upon myself to take them out for a test drive, as my sandals at the time were falling apart. I loved how comfy they were, and how they fit my foot perfectly, so I hopped online and ordered myself a pair. When I told my friend that I ordered them he let me know that I had made a mistake, as the dye in the straps constantly stain his feet black. I decided to give them a shot anyway, as they were a newer and different pair than his, and because my only other pair of sandals were in really bad shape. At first, the sandals didn't do anything to my feet, but that all changed on my first visit to the beach. When I got home I noticed big black spots on my feet that my girlfriend thought were bruises. They were hideous and hard to scrub off. It's been 4 months now and they still dye my feet really bad when they get wet. They will even leave small black marks when I wear them and keep them dry. There are too many comfortable sandals out there that don't stain your skin to waste your money on these. How the other reviewers on Amazon didn't notice this is beyond me... maybe they all live in Nevada. I'm just going to stop being cheap and shell out the $40+ for a nice pair of Rainbows.
