I got these in the black. I needed sandals with a back for work, because we aren't allowed to wear sandals without at least a back strap. I have other reef sandals that I LOVE because they're comfortable, so I went with these over other brands.  I was a bit worried at first because they seemed really tight and I thought "Oh NO! Should I have gotten adjustable ones???" because they don't have a buckle or anything.  I decided to bite the bullet and wear them anyway, and they loosened up a bit, and fit just fine now.  They are very comfortable and I don't feel any scrating or rubbing.  The only thing I don't like is they're a bit slippery when my feet get sweaty, but that's my problem, not the shoes. :)  Overall VERY happy with this purchase, only wish they were available in more colors so I can get even more (especially white...don't really have a need for the purple or peach)!!
*update-So I wore these a LOT and finally after a day of running around the golf course in them the toe strap did break out of the sole of the shoe like expressed from another reviewer on here.  I liked them so much though I bought another pair.  I wore those until I unexpectedly tripped on an edge in the sidewalk and did it again! this time it was the other shoe, so i went home and (having saved the first pair) tossed my broken shoes but still had the two in tact.  I have worn them all summer now and haven't had any problems.
