I wear a regular width size 8 99% of the time. I bought the 8 expecting these to be maybe a tiny bit loose. What no one seems to say is that the actual sole of these sandals is fairly NARROW...although the straps hold very well and have give to fit my feet, the sight of my (not wide width) feet hanging off the side of these shoes deterred me from keeping them. Also, I have plantar fascitis and although they felt comfy initially, walking for an hour in them aggravated the fascitis significantly since they're quite flat!
