I love the design of this case and the colors are beautiful! Literally smells like hot burning chemicals somewhere between gasoline and buring tires with a touch of sulfur. I haven’t yet tried them for a 3-hour period of walking and shopping; that’s my final comfort test. so that was weird. Most certainly not worth the cost (even if you can get them at an 80% discount). I use them for overnight and just use one, and they almost make it though the night. fit is true, durable and very comfortable. (Youll probably see this review if you click on the Purple/Black one as well) The size is perfect, and no slid9ng when I walk. So all in all, not bad!
