These sandals are super comfortable! I ordered the Black Rainbow color, and love that it's a traditional color with a playful side. The fabric is really soft, and there was no break-in period necessary. I was fearful the area between my toes would feel discomfort from the straps being too tight, but there was no issue. I was also worried there would be the 'clapping' noise that you get with regular flip flops, but that's not really the case (or at least, isn't evident). The sandals stayed on my feet with lots of walking (I didn't really try to jog or anything, so I can't tell you if the straps would have held up in that situation). I typically wear a 6.5 to 7, and am glad I went with the 7. Wearing a size 6 sandal wouldn't have fit.
