I don't know why I didn't listen to one of the other reviewers...

I just got my 7.5's and I, also, am going to exchange them for 7s.  I have a pair of 7.5 sneakers that my toe is about to pop through the canvas...but these sandals are quite roomy!  There's almost an inch from the tip of my toe to the end of the sandal...(but of course, you don't want your toes hanging off the edge).

Also, the color of the "sand dirty" is NOT at all a pinkish hue like it is in the image above.  It is the color of wet sand (darkish taupe?), but I suspect the color will lighten up with wear since it is suede.
