We walked lots and spent time on the beach. Mine works with the 3rd option. Bin sehr zufrieden, die Größe passt genau, ist rutschfest, Material riecht nicht extrem nach Kunststoff. mayor problema. This one is perfect! We needed a second set of headphones for him that he could use with his computer and be able hear what is going on whenever we do live a live stream together on my YouTube channel. It goes with my Decor in my home and I love it because its sturdy and easy to install. Some of us are trying to sleep. They come in half sizes which most slippers do not so this is really helpful to get the right fit. I got size 38 and theyre a tight fit but I can wear them.
