Im a 7. The arch support is really nice, from what I hear. While not the best sounding earphones that I have the Sabbat E12 are definitely getting the most time in my ears. Exactly what I had hoped. They DO NOT have noise cancelling capabilities like the ad states. Far less expensive than Apple originals and works very bit as well. The best slippers ever. These sounds really good, even for listening to music. i bought these shoes several months ago. First, these are NOT memory foam!
