The insert in the boot was very soft and form fitting to my foot. E già il secondo paio che acquisto perchè sono veramente molto comode. Added height is a plus, and they are very lightweight with a foam like bottom material. I just installed in a rental apartment that I have, so I will have to wait and see how well it holds up. I live in these the way some people live in their favorite sneakers. Plenty of other companies provide multiple cables for using their product to actually use it. They’re true to size so I know when I order my size they will always be a perfect fit. The way they work to cancel outside noise is incredible for this price range. Love it, you can sleep with them comfortably In fact I used only one of the two provided shelves.
