I?m usually a size 9 to 10, depending on the shoe. Very comfortable shoes, and nice looking also. It does a good job with noise cancellation too. And now a week later, I just bought a second pair. Simply put, with a good amp, these headphones are the best listening experience I have ever had, and they are noticeably more refined that the DT990s in every way. I cant say enough good things about them! In addition the area of the bottom inside part that connects to the top, is too high and rubs hard against both sides of both feet. These Anker Liberty 2 Pro earbuds do sound very good. The quality is not great for the money I?ve spend These are hands down the most comfortable shoes I own in general.
