These are comfortable for wearing around the house...although, I'm not sure if they are $33 worth of comfortable. They're comparable to the cheaper Nike flip-flops that I had before, but not *quite* as cushy, IMO. I usually have to size up when ordering flip-flops but I shouldn't have in this case...the 12 is too long and 11 would've fit perfectly. So I'd say they are definitely true to size.
