I have a hard time finding comfortable flip flops for summer so I tried these. They seemed uncomfortable to me because of the protrusions on the insole (they irritate the sole of the foot). Most flip flops these days have a smooth insole, but this particular sandal has some pretty rough cleats (so you don't slip, I think). I have another pair from the same brand with a floral insole and they are a bit smoother and more comfortable. My other complaint has to do with the size. I would prefer that
