Very comfy and supportive! I have narrow feet with high arches and these shoes support me unlike normal flat flip flops. I've had a pair of reefs that've lasted over 4 years now, I'm hopeing these last that long too! One review said these run a little small... not at all true. I wear a 8.5 right on the dot, and so I ordered the 9, and it's about half a size too big. I'm headed to hawaii in a few days and these will be my --all day everywhere shoes!!
