Tried this Crocs style and the Crocs Isabella (of which I already own in a the bronze/nude color but wanted a strappy sandal in black).  I much prefer the Crocs Sexi Flip style and color (a solid black rather than the translucent jelly black of the Isabella style), but it's just too tight!  If Crocs made half sizes, I suspect a 7.5 would fit perfectly!  But the 7 is too tight and the 8 is too long.  So I have to settle for the Isabella (in a size 7 which fits just fine!)
