Bought these on Amazon lightening deal. It also has a removable head, which is easy to clean with the brush it comes with. Slipped them on and wore them all day no chaffing or rubbing. But only had the shoe for 2 weeks and they are fallen apart! So then I took them to work so I could try to sell them and get my money back, and even a girl that wore a size 7. im not looking to push them into my brain, but the better they seal, they better they sound, so i like to get them tucked in. Use: This printer is self-explanatory and intuitive. To avoid it feeling wobbly, tighten each support as much as physically possible. I’m hoping these get more comfortable with wear, but so far I’m not able to do a whole lot of walking around in them before my feet start aching. The coiled cable isnt my preferred choice, but it seems of usable length and good quality.
