COMFORTABLE, its very important that I make that my first comment. They are super nice under my feet. My flat feet need ALL THE ASSISTANTS possible. There is a small arch that does its job. I am a flip flopping female ( Ill wear flip flops to court and a church ) these are my nice pair theyll do just right with that abercrombie kinda look you know after the beach look.  They are swell and I am so happy with my purchase. I wear a size 7 1/2 I got a size 8 and they're straight.
