Its very simple to plug in. They are very comfortable but are quite different from the the cork soled Madrid. They have easily supported the less than 1 lb items I have on them. We have those skinny hangers and Have had up to 10 hangers on it at a time. Give it a try, the waist trainer helps and stay position (doesnt roll up), It fits. It just kept searching for device. Second is the soundcore signature. It does everything it says and more! I grabbed these and a dust brush but I havent needed to dust my lenses or clean them since I started using this. I wear this shoe model without socks for hours directly out of box, without time needed to break them in, with my feet being on a wider, flat side, with a narrow heel.
