I got these for my daughter who broke her previous (well worn) pair of Havaianas.  The straps on the pair she got have an odd angle that causes them to rub on the top of the foot.  Both of us can wear this size and I recently swapped Havaianas with her while we were out because they were bothering her.  It wasn't just her that was bothered by these straps because I ended up with a blister on the top of my foot.<br /><br />Neither of us have had a problem with blisters from our Havaianas before but we have only had solid color straps.  These have two different colors, white on the bottom and silver on the top.  I think this may be why the straps angle in on top of the foot.<br /><br />I gave these 3 stars in part due to past experience with this brand of flip-flop.  Had I never owned Havaianas before... I wouldn't have been nearly so generous.
