SNUG FIT -- GO A SIZE UPQUALITY LOOKS GOOD -- A THIN LINER, NOT REALLY FLEECE AT ALLI bought from Amazon Warehouse and got a great price. New device works awesome. THERE IS NO WHERE ONE PLUS MENTIONED THAT MANUFACTURE WARRANTY IS DIFFERENT WHEN YOU BUY FROM AMAZON - VERY DISAPPOINTED Simple to use, just like the Airphones (but better looking and better musical performance). The material is great, and Im very careful, because if you catch something on it, it might run away, but the sewing needs to be strong, the material smooth, comfortable! This slippers are super comfy. I can see the LED light faintly but well enough to know when its charging. The two USB 2. I have foot problems so need something to support and cushion when I walk in my hardwood floors. Follow the size chart!
