Definitely not comfortable. I will be returning these shoes because without that support my foot continues to overpronate so show is distorted when worn. very simple to operate. I normally wear a size 6, but I tried one pair on at DSW and they were too big. And the beach aint about work. I wore them to the reception. Daughter loved her slippers! I can feel some air pressure coming from the back at high volume. tl;drSimultaneous device listening doesnt work at all. Initial impression, they fit just like the orginal style crocs!
