I ordered the red flip flop.  What I got was more coral.  I wear a size 8 1/2 shoe, so I ordered a 9.  The size fits perfect.  As for the comfort of the flip flop, this is the most comfortable shoe I have worn.  Even my boyfriend tried them on and said they was more comfortable than the pair I bought him last year.  I was a little hesitant with the thong between the toes.  I have worn some in the past and they were too tight or wore a blister on my feet.  This doesn't seem to be the issue.  These are extremely comfortable.  The padding for the sole of the shoe is super comfortable.  I don't have any issues wearing them all day long.  They don't make my back or knees hurt.

I did give them 4 stars due to the color difference.  What I got was definitely not red.  They are more orange or coral color.  The box said red.  However the color was not.  I wasn't going to send them back and try for another chance.  I was headed out of town this week and needing the flip flops.  The red was more of just a statement.  I try and stick with red since it's my favorite color.
