I was thrilled when I got these and put them on and they felt very comfortable. The red is a little paler than in the picture but that did not matter. However after a little while the back started rubbing and it became uncomfortable. I bought a 7 and usually wear a 7 if its made in China. Or a 6.5 if made in Brazil etc. If there were a 6.75 maybe it would be a better fit. My cousin recommended I put a "heal Cushion" in it. I am trying that today and see if its better.
